trusted-firmware-a: re-enable generation of packages

There is no need to inherit nopackages. Even when the output binaries are being
consumed from deploy or sysroot, and the main binary package is not meant to be
installed in the rootfs, package generation is still useful for SDK use cases
and as a way to distribute sources (e.g. src.rpm/SRPM) in Distros.

+meta-arm-autonomy Yocto Layer
+=============================
+
+Introduction
+------------
+This layer provides an hypervisor based solution (currently based on Xen) for
+autonomous system. It contains recipes and classes to build host and guests
+systems.
+
+To start using this layer, please check the
+[Quick Start Guide](documentation/arm-autonomy-quickstart.md).
+
+Dependencies
+------------
+This layer depends on several other Yocto layers:
+* meta-openembedded (https://git.openembedded.org/meta-openembedded)
+* poky (https://git.yoctoproject.org/poky)
+* meta-virtualization (https://git.yoctoproject.org/meta-virtualization)
+
+Distribution Features
+---------------------
+This layer is adding the following Yocto DISTRO_FEATURES:
+
+* arm-autonomy-host: this feature activates functionalities required to build
+  an autonomy host system. It is doing the following:
+  - add 'xen' and 'ipv4' to DISTRO_FEATURES.
+  - add xen backend drivers to linux kernel configuration.
+  - To reduce the root filesystem image size the kernel image is not installed.
+
+* arm-autonomy-guest: this feature activates functionalities to run as guest
+  of an autonomy system. It is doing the following:
+  - add 'ipv4' to DISTRO_FEATURES.
+  - add xen frontend drivers to linux kernel configuration.
+  - add console on hvc0 during init.
+
+Bitbake variables
+-----------------
+Some recipes and classes in this layer are introducing variables which can be
+modified by the user in local.conf.
+Each recipe introducing such variables has a chapter "Bitbake parameters" in
+its documentation.
+
+Those documentation files should be checked for variables:
+- [xen-devicetree](documentation/xen-devicetree.md)
+- [xenguest-manager](documentation/xenguest-manager.md)
+- [xenguest-network-bridge](documentation/xenguest-network-bridge.md)
+
+BSPs
+----
+This layer is adding the following machines:
+
+* arm64-autonomy-guest: this machines creates a minimal BSP suitable to be used
+  as an autonomy guest. It is in fact only activating ARM64 architecture and
+  SMP in the linux kernel and is enabling the DISTRO_FEATURE
+  arm-autonomy-guest.
+
+Images
+------
+This layer is adding the following images:
+
+* arm-autonomy-host-image-minimal: this image includes all elements required
+  to create a minimal arm-autonomy-host system. This includes xen and tools to
+  manage xen guests. This image depends on 'arm-autonomy-host' distribution
+  feature.
+
+Recipes and classes
+-------------------
+This layer is adding the following recipes and classes:
+
+* [xen-devicetree](documentation/xen-devicetree.md): this is a recipe to modify
+  a device tree blob to add information required to boot xen and a Dom0 linux.
+
+* [xenguest-mkimage](documentation/xenguest-mkimage.md): this is a tool to
+  create and modify images to be used as Xen guests.
+
+* [xenguest-manager](documentation/xenguest-manager.md): this is a tool to
+  create/remove/start/stop xen guest generated using xenguest-mkimage.
+
+* [xenguest-network-bridge](documentation/xenguest-network-bridge.md): this
+  recipe add tools and init scripts to create a bridge connected to the
+  external network on the host and allow guests to be connected to it.
+

+arm-autonomy Quick Start
+==================
+
+This documentation is explaining how to quickly start with arm-autonomy layer
+and the main features provided.
+You will find in the documentation directory some more detailed documentation
+for each of the functionalites provided by this layer.
+
+What to use this layer for?
+---------------------------
+Using this layer, you can easily and rapidly create a system based on Xen with
+one or more guests created using Yocto.
+
+For this you will need to create at least 2 Yocto projects:
+- a host project: This one will compile Xen and create a Linux system to be
+  used as Xen Dom0. The Linux system will contain all functionalities required
+  to start and manage guests.
+- one or several guest projects: Those will create Linux systems with the
+  required Linux kernel configuration to run as Xen DomU.
+
+Prepare your system
+-------------------
+
+First you must download the Yocto layers needed:
+ - [meta-openembedded](https://git.openembedded.org/meta-openembedded)
+ - [poky](https://git.yoctoproject.org/poky)
+ - [meta-virtualization](https://git.yoctoproject.org/meta-virtualization)
+ - [meta-arm](https://git.yoctoproject.org/meta-arm)
+ - all other layers you might want to use
+
+For each of the downloaded layer make sure you checkout the release of Yocto
+you want to use (for example zeus using `git checkout zeus`).
+
+Please follow [Yocto documentation](https://www.yoctoproject.org/docs/latest/brief-yoctoprojectqs/brief-yoctoprojectqs.html)
+in order to have the required dependencies.
+
+
+Create a project
+----------------
+
+Here are the main steps to create an arm-autonomy project:
+
+1. create a new Yocto project using `oe-init-build-env` in a new directory:
+  ```
+  oe-init-build-env my-project
+  ```
+
+2. Add `meta-arm/meta-arm-autonomy` layer to the list of layers of your
+  project in the `conf/bblayers.conf`. Also add any other layers you
+  might need (for example `meta-arm/meta-arm-bsp` and `meta-arm/meta-arm` to
+  use Arm boards like Juno or FVP emulator). You can achieve this by using
+  the `bitbake-layers add-layer layerdir [layerdir ...]` command.
+  For example:
+  ```
+  export LAYERDIR_BASE="/home/user/arm-autonomy/"
+  bitbake-layers add-layer $LAYERDIR_BASE/meta-poky $LAYERDIR_BASE/meta-yocto-bsp \
+   $LAYERDIR_BASE/meta-openembedded/meta-oe $LAYERDIR_BASE/meta-openembedded/meta-python \
+   $LAYERDIR_BASE/meta-openembedded/meta-filesystems $LAYERDIR_BASE/meta-openembedded/meta-networking \
+   $LAYERDIR_BASE/meta-virtualization $LAYERDIR_BASE/meta-arm/meta-arm-autonomy \
+   $LAYERDIR_BASE/meta-arm/meta-arm $LAYERDIR_BASE/meta-arm/meta-arm-bsp
+  ```
+
+  Example of a `conf/bblayers.conf`:
+  ```
+  BBLAYERS ?= " \
+    /home/user/arm-autonomy/poky/meta \
+    /home/user/arm-autonomy/poky/meta-poky \
+    /home/user/arm-autonomy/poky/meta-yocto-bsp \
+    /home/user/arm-autonomy/meta-openembedded/meta-oe \
+    /home/user/arm-autonomy/meta-openembedded/meta-python \
+    /home/user/arm-autonomy/meta-openembedded/meta-filesystems \
+    /home/user/arm-autonomy/meta-openembedded/meta-networking \
+    /home/user/arm-autonomy/meta-virtualization \
+    /home/user/arm-autonomy/meta-arm/meta-arm-autonomy \
+    /home/user/arm-autonomy/meta-arm/meta-arm \
+    /home/user/arm-autonomy/meta-arm/meta-arm-bsp \
+    "
+  ```
+
+Those steps will have to be done for each project you will have to create.
+
+Host project
+------------
+The host project will build Xen and the Dom0 Linux. It will be the only project
+that will be specific to the board (MACHINE) you will be running on.
+
+To create a host project:
+1. Follow the steps of "Create a project"
+
+2. Add the layers in `bblayers.conf` required to build a Yocto project for the
+   board you want to use.
+   For example to use Arm FVP Base emulator, add `meta-arm/meta-arm` and
+   `meta-arm/meta-arm-bsp`.
+
+3. edit conf/local.conf to add `arm-autonomy-host` to the DISTRO_FEATURES and
+   set MACHINE to the board you want to use.
+   For example, add the following lines:
+  ```
+  MACHINE = "fvp-base"
+  DISTRO_FEATURES += "arm-autonomy-host"
+  ```
+
+4. build the image using `bitbake arm-autonomy-host-image-minimal`
+
+The project will generate a Linux kernel, a root filesystem, a Xen binary and
+a DTB modified to include the required entries to boot Xen and Linux as Dom0
+(this DTB has the extension `-xen.dtb`).
+
+To boot the system using an u-boot base board you will need to:
+- Load the kernel (by default at 0x80080000 unless you modify
+  XEN_DEVICETREE_DOM0_ADDR value)
+- Load the xen device tree (for example at 0x83000000)
+- Load the xen-efi binary (for example at 0x84000000)
+- run using `booti 0x84000000 - 0x83000000`
+
+In this example the addresses might need to be adapted depending on your board.
+
+Guest project
+-------------
+The guest projects are not target specific and will use a Yocto MACHINE defined
+in meta-arm-autonomy to include only the Linux configuration required to run
+a xen guest.
+
+To create a guest project:
+
+1. Follow the steps of "Create a project"
+
+2. Optionaly add layers required to build the image and features you need.
+
+3. edit conf/local.conf to add `arm-autonomy-guest` to the DISTRO_FEATURES and
+   set MACHINE to `arm64-autonomy-guest`:
+  ```
+  MACHINE = "arm64-autonomy-guest"
+  DISTRO_FEATURES += "arm-autonomy-guest"
+  ```
+
+4. build the image you want.
+   For example `bitbake core-image-minimal`
+
+The build will create a ".xenguest" image that can be use on an host project
+with the xenguest-manager.
+
+Include guests directly in the host image
+-----------------------------------------
+The layer provides a way to directly include in the host project one or several
+images generated by guest projects.
+
+To use this feature, you must edit your host project `local.conf` file and
+add set ARM_AUTONOMY_HOST_IMAGE_EXTERN_GUESTS to the list of xenguest images
+you want to include in your host. Each xenguest image must be given using a
+full path to it.
+For example:
+```
+ARM_AUTONOMY_HOST_IMAGE_EXTERN_GUESTS = "/home/user/guest-project/tmp/deploy/images/arm64-autonomy-guest/core-image-minimal-arm64-autonomy-guest.xenguest;guestname=myguest"
+```
+This will add the guest and name it `myguest` on the host project image and
+the xenguest-manager will automatically boot it during startup.
+
+Add support for your board
+--------------------------
+Most of arm-autonomy layer is board independent but some functionalities
+might need to be customized for your board:
+
+### Add the kernel configuration for the host
+The layer is using KERNEL_FEATURES to add drivers required to be a Xen Dom0
+system.
+Depending on the kernel used by your BSP and how it is configured you might
+need to add the required drivers to your kernel configuration:
+- if KERNEL_FEATURES system is supported by your kernel, make sure that the
+file `recipes-kernel/linux/linux-arm-autonomy.inc` from the layer is included
+by your kernel recipe.
+- if it is not supported, you must add the proper drivers inside your kernel
+(modules are possible but they must be loaded before xenguest-manager is
+started). You can find the complete list of the kernel configuration elements
+required in `recipes-kernel/linux/arm-autonomy-kmeta/features/arm-autonomy/xen-host.cfg`.
+
+### Define the drive and partition to use for the LVM volume
+The xenguest-manager is creating disk hard drive using LVM on an empty
+partition. The default value is set to use /dev/sda2.
+You can change this for your board by setting XENGUEST_MANAGER_VOLUME_DEVICE.
+
+Check `recipes-extended/xenguest/xenguest-manager.bbappend` for examples.
+
+Please also read xenguest-manager.md.
+
+### Define the interface to add to xenguest network bridge
+xenguest-network bridge is creating a bridge on the host and adds network
+interfaces to it so that guest connected to it have access to external network.
+By default `eth0` is set as the list of interfaces to be added to the bridge.
+Depending on your board or use case you might want to use an other interface
+or use multiple interfaces.
+You can change this for your board by setting XENGUEST_NETWORK_BRIDGE_MEMBERS.
+
+Check `recipes-extended/xenguest/xenguest-network-bridge.bbappend` for
+exmaples.
+
+Please also read xenguest-network-bridge.md.
+
+### Define the network configuration of the xenguest network bridge
+xenguest network bridge is putting the host network interfaces in a bridge
+and is configuring it by default to use dhcp.
+If you need a different type of configuration you can set
+XENGUEST_NETWORK_BRIDGE_CONFIG in a xenguest-network-bridge.bbappend to use
+a different file.
+The recipe will look for the file in ${WORKDIR} so you will need to add it to 
+SRC_URI in your bbappend.
+The recipe will also substitute `###BRIDGE_NAME###` with the bridge name
+configured in ${XENGUEST_NETWORK_BRIDGE_NAME}.
+
+You can find an example configuration file in
+`recipes-extended/xenguest/files/xenguest-network-bridge-dhcp.cfg.in`.
+
+Please also read xenguest-network-bridge.md.
+
+### Customize Dom0 and Xen boot arguments for you board
+xen-devicetree is writting inside the generated DTB Xen and Linux boot
+arguments as long as the address where Dom0 Linux kernel can be found.
+You might need to have different values for your board or depending on your
+use case.
+
+You can find examples to customize this in
+`recipes-extended/xen-devicetree/xen-devicetree.bbappend`.
+
+Please also read xen-devicetree.md.

+Xen device tree
+===============
+
+Introduction
+------------
+
+xen-devicetree recipe can be used to modify an existing Device Tree Blob,
+produced by Linux kernel or another recipe, to include in it entries required
+to start Xen and a Dom0 Linux on top of it.
+
+The recipe will do the following processing:
+- generate a xen.dtsi file with entries required for xen based on parameters
+- turn DTBs in ${XEN_DEVICETREE_DTBS} back to dts
+- include in xen.dtsi and all other dtsi from
+  ${XEN_DEVICETREE_DTSI_MERGE} (check Bitbake parameters for more information
+  on this).
+- use dtc to create a new DTB file
+
+The recipe will generate new files in deploy/images and name them with the
+extension "-xen.dtb".
+For example **machine.dtb** will generate **machine-xen.dtb**.
+
+Entries added to the DTBs
+-------------------------
+
+When a DTB is processed by the recipe, the following block is added:
+```
+    chosen {
+        xen,dom0-bootargs = "VAL";
+        xen,xen-bootargs = "VAL";
+
+        modules {
+            #size-cells = <0x00000001>;
+            #address-cells = <0x00000001>;
+
+            module@0 {
+                reg = <VAL VAL>;
+                compatible = "multiboot,module";
+            };
+        };
+    };
+```
+Each occurence of **VAL** is replaced by the content of the variables listed in
+this documentation.
+
+Bitbake parameters
+------------------
+
+Several parameters are available to configure the xen-devicetree during Yocto
+project compilation (those can be set in your project local.conf, for exmple).
+
+The following parameters are available:
+
+- XEN_DEVICETREE_DEPEND: This variable can be used to indicate which recipe
+  task is generating the DTBs that xen-devicetree will modify. This makes sure
+  the xen devicetrees are properly regenerated if the source DTBs are changed.
+  This variable is set by default to "virtual/kernel:do_deploy" to use DTBs
+  generated during the compilation of the Linux kernel. This must be changed
+  if the machine your are using is not using a DTB listed in KERNEL_DEVICETREE.
+
+- XEN_DEVICETREE_DTBS: This should be set to the list of DTBs you want to be
+  modified by xen-devicetree. Those must be files that xen-devicetree can find
+  in the ${DEPLOY_DIR_IMAGE} directory using only the basename of the entries.
+  For example "mydir/board.dtb" will make the recipe look for
+  ${DEPLOY_DIR_IMAGE}/board.dtb.
+  This variable is set by default to "${KERNEL_DEVICETREE}" to process the DTBs
+  generated by the Linux kernel.
+
+- XEN_DEVICETREE_DOM0_MEM: Memory size to allocate to Dom0.
+  This variable is only used if XEN_DEVICETREE_XEN_BOOTARGS has a value
+  containing "dom0_mem=${XEN_DEVICETREE_DOM0_MEM}" as the memory assigned to
+  dom0 is defined using Xen boot arguments.
+  This variable is set by default to "1024M".
+
+- XEN_DEVICETREE_DOM0_BOOTARGS: Boot arguments to pass to Dom0 Linux when
+  booting it.
+  This variable is set by default to "console=hvc0 earlycon=xen".
+
+- XEN_DEVICETREE_XEN_BOOTARGS: this variable should be set with the boot
+  arguments to be passed to Xen on boot.
+  This variable is set by default to
+  "noreboot dom0_mem=${XEN_DEVICETREE_DOM0_MEM}".
+
+- XEN_DEVICETREE_DOM0_ADDR: This is the address from which the Linux kernel to
+  be used for Dom0 will be copied. When using u-boot, this is the address at
+  which you will load the kernel Image before starting Xen.
+  This variable is set by default to "0x80080000".
+
+- XEN_DEVICETREE_DOM0_SIZE: This is the size of the kernel loaded at
+  ${XEN_DEVICETREE_DOM0_ADDR}. Xen will copy this amount of data inside the
+  guest before starting it so the size must be at least equal to the kernel
+  size but can be bigger. You must be careful not to have a value too big as it
+  could slow down boot or copy other parts with it (like the DTB).
+  You might need to increase this if you use a kernel with a bundled initramfs.
+  This variable is set by default to "0x01000000".
+
+- XEN_DEVICETREE_DTSI_MERGE: This variable contains the list of dtsi files that
+  must be included inside the generated DTB file. By default the only one
+  include is the "xen.dtsi" generated by the recipe.
+  If your board or project needs to include more fixes or entries in the DTB,
+  this variable can be appended from a bbappend file to include other dtsi. The
+  files must be inside the recipe workspace during Yocto compilation.
+  You can check xen-devicetree.bbappend for an example.

+Xenguest Manager
+================
+
+Introduction
+------------
+
+xenguest-manager is a tool to manage Xenguest images generated by
+[xenguest-mkimage](xenguest-mkimage.md).
+
+On a Xen Dom0 system it will:
+- create a xen guest from a xenguest image: extract its components, create a
+  disk for the guest using LVM volumes.
+- start/stop a xen guest (during init or using xenguest-manager directly).
+- check guest status
+
+xenguest-manager is composed of 2 shell scripts:
+- xenguest-manager which can be used from command line to start/stop/check
+guests and create or remove guest using xenguest images.
+- xenguest-init which is called during init to automatically create and start
+some guests as part of the host init process.
+
+Usage
+-----
+
+xenguest-manager must be called like this:
+`xenguest-manager OPERATION [OPTIONS]`
+The following operations are available:
+- create XENGUEST_IMAGE [GUESTNAME]: create a guest from a xenguest image file
+  as guest GUESTNAME. If GUESTNAME is not given the image file name is used
+  without the xenguest extension.
+- remove GUESTNAME: remove the guest GUESTNAME.
+- start GUESTNAME: start the guest GUESTNAME.
+- stop GUESTNAME: stop the guest GUESTNAME (this is using `xl stop` which is
+  sending a stop signal to the running guest).
+- kill GUESTNAME: force stopping the guest GUESTNAME.
+- list: list the available guests.
+- status [GUESTNAME]: print the current status of GUESTNAME. If GUESTNAME is
+  not given, print the status of all guests.
+
+For a detailed help on available options please use:
+`xenguest-manager --help`
+
+Bitbake parameters
+------------------
+
+Several parameters are available to configure the xenguest manager during Yocto
+project compilation (those can be set in your project local.conf, for example).
+
+The following parameters are available:
+
+- XENGUEST_MANAGER_VOLUME_DEVICE: This is the device path used by the 
+  xenguest-manager on the device to create LVM disks when guests have a disk
+  configuration.
+  This is set by default to "/dev/sda2".
+
+- XENGUEST_MANAGER_VOLUME_NAME: This is the LVM volume name that the 
+  xenguest-manager will create and use to create guest LVM disks.
+  This is set by default to "vg-xen".
+
+- XENGUEST_MANAGER_GUEST_DIR: This is the directory on Dom0 where the 
+  xenguest-manager will look for xenguest images to create during init. That's
+  the place where xenguest images can be added to have them automatically
+  created during next Dom0 boot. The xenguests found there will only be created
+  if they were not already before (the basename of the files is used as guest
+  name).
+  This is set by default to "/usr/share/guests".

+Xenguest mkimage
+================
+
+Introduction
+------------
+
+xenguest-mkimage is a tool to create and modify images to be used as Guest with
+Xen. It defines a format to store completely defined guests as a file or as
+a directory and provides options to create and modify those images.
+
+A xenguest image contains all elements required to create a xen guest.
+This is the base elements like a Xen configuration and a Linux kernel binary
+but also some more advanced elements like init scripts or a disk definition.
+
+The format is made to be deployable easily by storing everything in a single
+file and provide tools to easily manipulate the images. It can also easily be
+extended to have features like encryption or signature of images, updates or
+complex configurations by providing features to have init script that will be
+executed on the host embedded inside the image.
+
+Xenguest images content
+-----------------------
+
+### params.cfg
+
+This file contains parameters that can be used by tools to configure some
+functionalities on the host. This can be used by init scripts to have
+configurable parameters as it is sourced before calling init scripts.
+
+### guest.cfg and guest.d
+
+guest.cfg is the main xen configuration and guest.d contains optional
+configuration parts. All those will be merged into one final xen configuration
+before starting the guest.
+
+### files
+This directory contains files that can be used by the xen configuration, for
+example the binary of the kernel referenced in xen configuration).
+This is where the kernel binary, the dtb or a ramdisk will be stored.
+
+### init.pre, init.d and init.post
+These directories contain init scripts that will be executed on the host
+during the guest startup. Those must be shell scripts and each directory
+contains scripts called at a different time:
+ - init.pre: scripts executed before the guest is created. This can be used
+     to prepare some features required to create the guest in xen or to
+     generate part of the xen configuration dynamically.
+ - init.d: scripts executed when the guest has been created but before it is
+     started. This can be used to do some xenstore operations or configure the
+     guest behaviour using xl, for example.
+ - init.post: scripts executed just after starting the guest. This can be
+     used to configure things created by xen for the guest like network
+     network interfaces.
+
+When a directory contains several scripts, those will be called in alphabetical
+order.
+
+### disk.cfg and disk-files
+disk.cfg contains the guest disk description (disk size and disk partitions).
+The file contains the following entries:
+- `DISK_SIZE=X`: size of the disk to create in GB
+- `DISK_PARTX=SIZE:FS:CONTENT`: create a partition number X (1 to 4) with a
+  size of SIZE GB, format it with filesystem FS (can be ext2, ext3, ext4, vfat
+  or swap) and extract CONTENT as initial partition content
+  (.tar[.gz|.xz|.bz2] file or img[.gz|.bz2] file to be dumped in the partition). FS and
+  CONTENT can be empty.
+
+The disk-files contain files to be used for initializing the disk partitions
+content. Those should be used to create a LVM or a physical disk and initialize
+it (create partitions, format them and put the initial content).
+
+Usage
+-----
+
+xenguest-mkimage is a shell script which must be called like this:
+`xenguest-mkimage OPERATION XENGUEST [OPTIONS]`
+
+### Operations
+- create: create a xenguest image. If XENGUEST is an existing empty directory,
+  the image is created as a directory otherwise it will be created as a file.
+- check: verify that XENGUEST is a valid xenguest image.
+- update: modify a xenguest image (see --help for a list of operations).
+- pack: pack a xenguest image directory into a xenguest image file. The file to
+  be created must be given as 3rd argument.
+- extract: extract a xenguest image file into a directory. The destination
+  directory must be given as 3rd argument.
+- dump-xenconfig: dump xenguest image xen configuration.
+- dump-diskconfig: dump xenguest image disk configuration.
+- dump-paramsconfig: dump xenguest image parameters configuration.
+
+For a detailed help on available operations, please use:
+`xenguest-mkimage --help`
+
+### Options
+- --kernel=FILE: add kernel FILE as guest kernel. This is both adding the file
+  to the image and modifying the xen configuration to use it.
+- --xen-memory=SIZE: set the guest memory size in MB.
+- --xen-extra: add a kernel command line argument. This can be called several
+  times to add several command line options.
+- --xen-device-tree=FILE: add dtb FILE as device tree. This both adding the
+  file to the image and modifying the xen configuration to use it.
+- --init-script=FILE: add guest init script. The script is embedded inside the
+  image file. Several script can be added and the basename of FILE is used to
+  distinguish them (calling the option twice with the same file will update the
+  script in the image with the second one).
+ --disk-size=SIZE: set the guest disk size to SIZE in GB. Calling this with 0
+  disable the guest disk.
+- --disk-add-part=NUM:SIZE:FS:CONTENT: This is adding a partition to the
+  xenguest image disk. The partition is described with the arguments:
+  - NUM: partition number.
+  - SIZE: partition size in GB.
+  - FS: filesystem to format the partition with. This can be ext2, ext3, ext4,
+    vfat of swap. If empty the partition is not formated.
+  - CONTENT: tar of img file to use to initialize the partition. The file must
+    be added to the image using --disk-add-file=FILE:CONTENT.

+xenguest network bridge
+=======================
+
+Introduction
+------------
+
+xenguest-network-bridge is creating a network bridge to allow some guests to
+have a direct connection to the external network.
+To do this, a bridge is created on the host using brctl with the network
+interfaces added to it so that the bridge is connected to the external network.
+It is also adding a guest init script which will, for guests configured to use
+it, create a virtual network interface for the guest and connect it to the
+network bridge on the host.
+
+Usage
+-----
+
+On the host the package xenguest-network-bridge must be included in your image.
+
+On the xenguest image of your guest, the parameter NETWORK_BRIDGE must be set
+to 1 (using xenguest-mkimage --set-param=NETWORK_BRIDGE=1).
+
+Bitbake parameters
+------------------
+Several parameters are available to configure the xenguest network bridge
+during Yocto project compilation (those can be set in your project local.conf,
+for example).
+
+The following parameters are available:
+
+- XENGUEST_NETWORK_BRIDGE_NAME: This variable defines the name of the network
+  bridge that is created on the host during init.
+  This is set by default to "xenbr0".
+
+- XENGUEST_NETWORK_BRIDGE_MEMBERS: This variable defines the list of network
+  interfaces that are added to the bridge when it is created on the host during
+  init.
+  This is set by default to "eth0".
+
+- XENGUEST_NETWORK_BRIDGE_CONFIG: This variable defines the configuration file
+  to use to configure the bridge network. By default it points to have file
+  configuring the network using dhcp.
+  You can provide a different file using a bbappend and make this variable
+  point to it if you want to customize your network configuration.
+
+- XENGUEST_IMAGE_NETWORK_BRIDGE: This variable can be set to 0 or 1 on guest
+  projects to enable or not the connection of the guest to the host bridge.
+  This is set by default to "1".

+Subject: [PATCH] xen/arm: Cap the number of interrupt lines for dom0
+
+Dom0 vGIC will use the same number of interrupt lines as the hardware GIC.
+While the hardware GIC can support up to 1020 interrupt lines,
+the vGIC is only supporting up to 992 interrupt lines.
+This means that Xen will not be able to boot on platforms where the hardware
+GIC supports more than 992 interrupt lines.
+While it would make sense to increase the limits in the vGICs, this is not
+trivial because of the design choices.
+At the moment, only models seem to report the maximum of interrupt lines.
+They also do not have any interrupt wired above the 992 limit.
+So it should be fine to cap the number of interrupt lines for dom0 to 992 lines.

+                         --xen-extra=console=ttyS0 --xen-extra=rw
+--xen-root=             disable root parameter in xen configuration
+--xen-root=ROOT         set guest root in xen configuration
+--xen-device-tree=      disable device tree parameter in xen configuration
+--xen-device-tree=FILE  set guest device tree in xen configuration and add
+                         file to xen files
+--xen-disk=             disable disk parameter in xen configuration
+--xen-disk=DEV          set guest disk to device DEV (phy:DEV,xvda,w is set)
+--xen-append=FILE       append FILE content to xen configuration
+
+Xen files
+--xen-add-file=SRC:DST  add file SRC as file DST in the xenguest image.
+                         If DST already exist in the image, it is overwritten.
+                         DST must be the same as arguments passed to other
+                         options (like --xen-kernel)
+--xen-rm-file=DST       remove file DST from the xenguest image.
+
+Init configuration
+  This can be used to add init scripts for the guest. There are 3 possible init
+  scripts which are called at different time. The pre scripts are called first,
+  then the xen guest is created in pause and standard init scripts are called.
+  Finally the xen guest is started then the post init scripts are called.
+  Each script is called with the name of the guest as first argument and
+  multiple scripts can be added (they must have different names).
+
+--init-script=FILE      add FILE as init script
+--init-pre=FILE         add FILE as pre init script
+--init-post=FILE        add FILE as post init script
+
+Disk configuration
+--disk-reset-config     reset disk guest configuration to default (no disk)
+--disk-size=SZ          set guest disk size (in GB)
+--disk-device=DEV       set device to be used to create the guest disk
+                        if unset or set to an empty string, the volume will be
+                        create in the default manager volume group.
+--disk-add-part=DEF     add a partition to the guest disk with definition DEF
+                         a partition definition must have the following format:
+                         ID:SIZE:FORMAT:CONTENT where:
+                         - ID is the partition numeric ID (1 to 4)
+                         - FORMAT is the filesystem format (supported formats
+                           are none, vfat, swap, ext2, ext3 and ext4) or can be
+                           left empty to not format
+                         - CONTENT can be used to point to a file added using
+                          --disk-add-file to be used as partition initial
+                          content (tar file or img file)
+--disk-rm-part=ID       remove partition ID from the guest disk
+--disk-add-file=SRC:DST add file SRC as disk file DST in the xenguest image.
+                         DST can then be used as a partition CONTENT.
+--disk--rm-file=DST     remove disk file DST from the xenguest image.

+
+### Build:

+
+### Run:
+To Run the Fixed Virtual Platform simulation tool you must download "Armv8-A
+Foundation Platform" from Arm developer (This might require the user to
+register) from this address:
+https://developer.arm.com/tools-and-software/simulation-models/fixed-virtual-platforms
+and install it on your host PC.
+
+Fast Models Fixed Virtual Platforms (FVP) Reference Guide:
+https://developer.arm.com/docs/100966/latest
+
+Armv8‑A Foundation Platform User Guide:
+https://developer.arm.com/docs/100961/latest/
+
+
+Once done, do the following to build and run an image:
+```bash$ bitbake core-image-minimal```
+```bash$ export YOCTO_DEPLOY_IMGS_DIR="<yocto-build-dir/tmp/deploy/images/foundation-v8>"```
+```bash$ cd <path-to-Foundation_Platformpkg-dir/models/Linux64_GCC-X.X/>```
+```
+bash$ ./Foundation_Platform --cores=4 --no-sve --gicv3 \
+         --data=${YOCTO_DEPLOY_IMGS_DIR}/bl1-fvp.bin@0x0 \
+         --data=${YOCTO_DEPLOY_IMGS_DIR}/Image@0x80080000 \

+         --block-device=${YOCTO_DEPLOY_IMGS_DIR}/core-image-minimal-foundation-armv8.disk.img \
+```
+
+If you have built a configuration without a ramdisk, you can use the following
+command in U-boot to start Linux:
+```VExpress64# booti 0x80080000 - 0x83000000```
+

+```bash$ bitbake core-image-minimal```
+```bash$ export YOCTO_DEPLOY_IMGS_DIR="<yocto-build-dir/tmp/deploy/images/fvp-base>"```
+```bash$ cd <path-to-Base_RevC_AEMv8A_pkg-dir/models/Linux64_GCC-X.X/>```

+# Juno Development Platform Support in meta-arm-platforms
+
+## Howto Build and Run
+
+### Configuration:
+In the local.conf file, MACHINE should be set as follow:
+MACHINE ?= "juno"
+
+Juno is using a USB hard drive for root filesystem by default. The distribution
+used must have ```usbhost``` and ```usbgadget``` in DISTRO_FEATURES (this is
+the case in poky distribution).
+
+### Build:
+```bash$ bitbake core-image-minimal```
+
+### Update Juno SD card:
+
+The SD card content is generated during the build here:
+tmp/deploy/images/juno/firmware-image-juno.tar.gz
+
+Its content must be written on the Juno firmware SD card.
+To do this:
+- insert the sdcard of the Juno in an SD card reader and mount it:
+```bash$ sudo mount /dev/sdx1 /mnt```
+(replace sdx by the device of the SD card)
+
+- erase its content and put the new one:
+```bash$ sudo rm -rf /mnt/*```
+```bash$ sudo tar --no-same-owner -xzf tmp/deploy/images/juno/firmware-image-juno.tar.gz -C /mnt/```
+```bash$ sudo umount /mnt```
+
+- reinsert the SD card in the Juno board
+
+### Create an USB hard drive:
+
+Linux root file system should be stored on the second partition of an USB
+drive that must be plugged on the Juno Platform.
+
+This partition should be initialized with the content of the filesystem
+generated by yocto that you can find here:
+tmp/deploy/images/juno/core-image-minimal-juno.tar.bz2
+
+To do this
+- Format a USB disk, create two primary partitions (ext4).
+- mount the secondary partition
+- untar tmp/deploy/images/juno/core-image-minimal-juno.tar.bz2 on to the
+  secondary partition.
+
+### Run:
+You must insert the SD card and the USB drive and power-on the Juno board.
+The console should be available on the second serial line:
+screen -L /dev/tty.usbserial 115200
+
+On the first boot the images will be flashed which can take some time.
+
+## Devices supported in the kernel
+- serial
+- usb
+- network
+- watchdog
+- rtc
+- mmc
+
+### Untested:
+- i2c
+- dma
+- pci
+- sata
+- sound
+
+## Devices not supported or not functional
+- framebuffer: not functional
+    The HDMI is not properly detected.
+- GPU (no user land libraries).
+    The mali-midgard-kernel can be used to have a kernel driver

+Subject: [PATCH] plat/arm: a5ds: move dtb to a new address
+
+When Using bigger kernel images (>8.4MB compressed zImage) and at
+decompress and final location init stage of kernel start makes it
+override dtb at this address, to avoid this move the dtb a little
+higher in address related.
