external-arm-toolchain: Misc. fixup for GCC 10.2 support

Arm GCC 10.2 prebuilt toolchain comes with ldd and tzselect scripts which uses "/usr/bin/bash", so replace this with "/bin/sh" as the default shell. Signed-off-by: Sumit Garg <sumit.garg@linaro.org> Signed-off-by: Jon Mason <jon.mason@arm.com>

-
-If you're building procps with a newer glibc (with pidfd_open()) but
-older kernel headers (say 4.x, before __NR_pidfd_open) then procps will
-fail to build because of a typo in configure.ac.

-# Reporting vulnerabilities
-
-Arm takes security issues seriously and welcomes feedback from researchers and
-the security community in order to improve the security of its products and
-services. We operate a coordinated disclosure policy for disclosing
-vulnerabilities and other security issues.
-
-Security issues can be complex and one single timescale doesn't fit all
-circumstances. We will make best endeavours to inform you when we expect
-security notifications and fixes to be available and facilitate coordinated
-disclosure when notifications and patches/mitigations are available.
-
-
-## How to Report a Potential Vulnerability?
-
-If you would like to report a public issue (for example, one with a released CVE
-number), please contact the meta-arm mailing list at
-meta-arm@lists.yoctoproject.org and arm-security@arm.com.
-
-If you are dealing with a not-yet released or urgent issue, please send a mail
-to the maintainers (see README.md) and arm-security@arm.com, including as much
-detail as possible.  Encrypted emails using PGP are welcome.
-
-For more information, please visit https://developer.arm.com/support/arm-security-updates/report-security-vulnerabilities.
-
-
-## Branches maintained with security fixes
-
-meta-arm follows the Yocto release model, so see
-[https://wiki.yoctoproject.org/wiki/Stable_Release_and_LTS Stable release and
-LTS] for detailed info regarding the policies and maintenance of stable
-branches.
-
-The [https://wiki.yoctoproject.org/wiki/Releases Release page] contains a list of all
-releases of the Yocto Project. Versions in grey are no longer actively maintained with
-security patches, but well-tested patches may still be accepted for them for
-significant issues.

-# OEQA on Arm FVPs
-
-OE-Core's [oeqa][OEQA] framework provides a method of performing runtime tests on machines using the `testimage` Yocto task. meta-arm has good support for writing test cases against [Arm FVPs][FVP], meaning the [runfvp][RUNFVP] boot configuration can be re-used.
-
-Tests can be configured to run automatically post-build by setting the variable `TESTIMAGE_AUTO="1"`, e.g. in your Kas file or local.conf.
-
-meta-arm provides the OEFVPTarget which must be set up in the machine configuration:
-```
-TEST_TARGET = "OEFVPTarget"
-TEST_SERVER_IP = "127.0.0.1"
-TEST_TARGET_IP = "127.0.0.1:2222"
-IMAGE_FEATURES:append = " ssh-server-dropbear"
-FVP_CONFIG[bp.virtio_net.hostbridge.userNetPorts] ?= "2222=22"
-FVP_CONSOLES[default] = "terminal_0"
-FVP_CONSOLES[tf-a] = "s_terminal_0"
-```
-
-The test target also generates a log file with the prefix 'fvp_log' in the image recipe's `${WORKDIR}/testimage` containing the FVP's stdout.
-
-OEFVPTarget supports two different test interfaces - SSH and pexpect.
-
-## SSH
-
-As in OEQA in OE-core, tests cases can run commands on the machine using SSH. It therefore requires that an SSH server is installed in the image.
-
-This uses the `run` method on the target, e.g:
-```
-(status, output) = self.target.run('uname -a')
-```
-which executes a single command on the target (using `ssh -c`) and returns the status code and the output. It is therefore useful for running tests in a Linux environment.
-
-For examples of test cases, see meta/lib/oeqa/runtime/cases in OE-Core. The majority of test cases depend on `ssh.SSHTest.test_ssh`, which first validates that the SSH connection is functioning.
-
-## pexpect
-
-To support firmware and baremetal testing, OEFVPTarget also allows test cases to make assertions against one or more consoles using the pexpect library.
-
-Internally, this test target launches a [Pexpect][PEXPECT] instance for each entry in FVP_CONSOLES which can be used with the provided alias. The whole Pexpect API is exposed on the target, where the alias is always passed as the first argument, e.g.:
-```
-self.target.expect('default', r'root@.*\:~#', timeout=30)
-self.assertNotIn(b'ERROR:', self.target.before('tf-a'))
-```
-
-For an example of a full test case, see meta-arm/lib/oeqa/runtime/cases/linuxboot.py This test case can be used to minimally verify that a machine boots to a Linux shell. The default timeout is 10 minutes, but this can be configured with the variable TEST_FVP_LINUX_BOOT_TIMEOUT, which expects a value in seconds.

-# Running Images with a FVP
-
-The `runfvp` tool in meta-arm makes it easy to run Yocto Project disk images inside a [Fixed Virtual Platform (FVP)][FVP].  Some FVPs, such as the [Arm Architecture Models][AEM], are available free to download, but others need registration or are only available commercially.  The `fvp-base` machine in meta-arm-bsp uses one of these AEM models.
-
-## Running images with `runfvp`
-
-To build images with the FVP integration, the `fvpboot` class needs to be inherited.  If the machine does not do this explicitly it can be done in `local.conf`:
-
-```
-INHERIT += "fvpboot"
-```
-
-The class will download the correct FVP and write a `.fvpconf` configuration file when an image is built.
-
-To run an image in a FVP, pass either a machine name or a `.fvpconf` path to `runfvp`.
-
-```
-$ ./meta-arm/scripts/runfvp tmp/deploy/images/fvp-base/core-image-minimal-fvp-base.fvpconf
-```
-
-When a machine name is passed, `runfvp` will start the latest image that has been built for that machine. This requires that the BitBake environment has been initialized (using `oe-init-build-env` or similar) as it will start BitBake to determine where the images are.
-
-```
-$ ./meta-arm/scripts/runfvp fvp-base
-```
-
-Note that currently meta-arm's `scripts` directory isn't in `PATH`, so a full path needs to be used.
-
-`runfvp` will automatically start terminals connected to each of the serial ports that the machine specifies.  This can be controlled by using the `--terminals` option, for example `--terminals=none` will mean no terminals are started, and `--terminals=tmux` will start the terminals in [`tmux`][tmux] sessions.  Alternatively, passing `--console` will connect the serial port directly to the current session, without needing to open further windows.
-
-The default terminal can also be configured by writing a [INI-style][INI] configuration file to `~/.config/runfvp.conf`:
-
-```
-[RunFVP]
-Terminal=tmux
-```
-
-Arbitrary options can be passed directly to the FVP by specifying them after a double dash, for example this will list all of the FVP parameters:
-
-```
-$ runfvp fvp-base -- --list-params
-```
-
-## Configuring machines with `fvpboot`
-
-To configure a machine so that it can be ran inside `runfvp`, a number of variables need to be set in the machine configuration file (such as `meta-arm-bsp/conf/machine/fvp-base.conf`).
-
-Note that at present these variables are not stable and their behaviour may be changed in the future.
-
-### `FVP_EXE`
-
-The name of the FVP binary itself, for example `fvp-base` uses `FVP_Base_RevC-2xAEMvA`.
-
-### `FVP_PROVIDER`
-
-The name of the recipe that provides the FVP executable set in `FVP_EXE`, for example `fvp-base` uses `fvp-base-a-aem-native`.  This *must* be a `-native` recipe as the binary will be executed on the build host.
-
-There are recipes for common FVPs in meta-arm already, and writing new recipes is trivial.  For FVPs which are free to download `fvp-base-a-aem.bb` is a good example. Some FVPs must be downloaded separately as they need an account on Arm's website.
-
-If `FVP_PROVIDER` is not set then it is assumed that `FVP_EXE` is installed on the host already.
-
-### `FVP_CONFIG`
-
-Parameters passed to the FVP with the `--parameter`/`-C` option.  These are expressed as variable flags so individual parameters can be altered easily. For example:
-
-```
-FVP_CONFIG[bp.flashloader0.fname] = "fip-fvp.bin"
-```
-
-### `FVP_DATA`
-
-Specify raw data to load at the specified address, passed to the FVP with the `--data` option.  This is a space-separated list of parameters in the format `[INST=]FILE@[MEMSPACE:]ADDRESS`. For example:
-
-```
-FVP_DATA = "cluster0.cpu0=Image@0x80080000 \
-            cluster0.cpu0=fvp-base-revc.dtb@0x83000000"
-```
-
-### `FVP_APPLICATIONS`
-
-Applications to load on the cores, passed to the FVP with the `--application` option.  These are expressed as variable flags with the flag name being the instance and flag value the filename, for example:
-
-```
-FVP_APPLICATIONS[cluster0] = "linux-system.axf"
-```
-
-Note that symbols are not allowed in flag names, so if you need to use a wildcard in the instance then you'll need to use `FVP_EXTRA_ARGS` and `--application` directly.
-
-### `FVP_TERMINALS`
-
-Map hardware serial ports to abstract names. For example the `FVP_Base_RevC-2xAEMvA` FVP exposes four serial ports, `terminal_0` to `terminal_3`.  Typically only `terminal_0` is used in the `fvp-base` machine so this can be named `"Console"` and the others `""`.  When runfvp starts terminals it will only start named serial ports, so instead of opening four windows where only one is useful, it will only open one.
-
-For example:
-```
-FVP_TERMINALS[bp.terminal_0] = "Console"
-FVP_TERMINALS[bp.terminal_1] = ""
-FVP_TERMINALS[bp.terminal_2] = ""
-FVP_TERMINALS[bp.terminal_3] = ""
-```
-
-### `FVP_CONSOLES`
-
-This specifies what serial ports can be used in oeqa tests, along with an alias to be used in the test cases. Note that the values have to be the FVP identifier but without the board prefix, for example:
-```
-FVP_CONSOLES[default] = "terminal_0"
-FVP_CONSOLES[tf-a] = "s_terminal_0"
-```
-
-The 'default' console is also used when `--console` is passed to runfvp.
-
-### `FVP_EXTRA_ARGS`
-
-Arbitrary extra arguments that are passed directly to the FVP.  For example:
-
-```
-FVP_EXTRA_ARGS = "--simlimit 60"
-```
-
-### `FVP_ENV_PASSTHROUGH`
-
-The FVP is launched with an isolated set of environment variables. Add the name of a Bitbake variable to this list to pass it through to the FVP environment. For example:
-
-```
-FVP_ENV_PASSTHROUGH = "ARMLMD_LICENSE_FILE FM_TRACE_PLUGINS"
-```

-# The Trusted Services: framework for developing root-of-trust services
-
-meta-arm layer includes recipes for [Trusted Services][^1] Secure Partitions and Normal World applications
-in `meta-arm/recipes-security/trusted-services`
-
-## Secure Partitions recipes
-
-We define dedicated recipes for all supported Trusted Services (TS) Secure Partitions.
-These recipes produce ELF and DTB files for SPs.
-These files are automatically included into optee-os image accordingly to defined MACHINE_FEATURES.
-
-### How to include TS SPs
-
-To include TS SPs into optee-os image you need to add into MACHINE_FEATURES
-features for each [Secure Partition][^2] you would like to include:
-
-| Secure Partition  | MACHINE_FEATURE |
-| ----------------- | --------------- |
-| Attestation       | ts-attesation   |
-| Crypto            | ts-crypto       |
-| Firmware Update   | ts-fwu
-| Internal Storage  | ts-its          |
-| Protected Storage | ts-storage      |
-| se-proxy          | ts-se-proxy     |
-| smm-gateway       | ts-smm-gateway  |
-| spm-test[1-4]     | optee-spmc-test |
-
-Other steps depend on your machine/platform definition:
-
-1. For communications between Secure and Normal Words Linux kernel option `CONFIG_ARM_FFA_TRANSPORT=y`
-   is required. If your platform doesn't include it already you can add `arm-ffa` into MACHINE_FEATURES.
-   (Please see ` meta-arm/recipes-kernel/arm-tstee`.)
-
-   For running the `uefi-test` or the `xtest -t ffa_spmc` tests under Linux the `arm-ffa-user` drivel is required. This is
-   enabled if the `ts-smm-gateway` and/or the `optee-spmc-test` machine features are enabled.
-   (Please see ` meta-arm/recipes-kernel/arm-ffa-user`.)
-
-2. optee-os might require platform specific OP-TEE build parameters (for example what SEL the SPM Core is implemented at).
-   You can find examples in `meta-arm/recipes-security/optee/optee-os_%.bbappend` for qemuarm64-secureboot machine
-   and in `meta-arm-bsp/recipes-security/optee/optee-os-n1sdp.inc` and `meta-arm-bsp/recipes-security/optee/optee-os-corstone1000-common.inc`
-   for N1SDP and Corstone1000 platforms accordingly.
-
-3. trusted-firmware-a might require platform specific TF-A build parameters (SPD and SPMC details on the platform).
-   See `meta-arm/recipes-bsp/trusted-firmware-a/trusted-firmware-a_%.bbappend` for qemuarm64-secureboot machine
-   and in `meta-arm-bsp/recipes-bsp/trusted-firmware-a/trusted-firmware-a-n1sdp.inc` and
-   `meta-arm-bsp/recipes-bsp/trusted-firmware-a/trusted-firmware-a-corstone1000.inc` for N1SDP and Corstone1000 platforms.
-
-4. Trusted Services supports an SPMC agonistic binary format. To build SPs to this format the `TS_ENV` variable is to be
-   set to `sp`. The resulting SP binaries should be able to boot under any FF-A v1.1 compliant SPMC implementation.
-
-
-## Normal World applications
-
-Optionally for testing purposes you can add `packagegroup-ts-tests` into your image. It includes
-[Trusted Services test and demo tools][^3] and [xtest][^4] configured to include the `ffa_spmc` tests.
-
-## OEQA Trusted Services tests
-
-  meta-arm also includes Trusted Service OEQA tests which can be used for automated testing.
-See `ci/trusted-services.yml` for an example how to include them into an image.

+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 Multiconfig Build Environment Instructions
+==================
+
+This documentation explains how to simplify the process of building hosts
+and guests in a single bitbake command, rather than in seperate build
+folders. You can read more about multiconfig in the bitbake documentation:
+
+ - [bitbake user manual](https://www.yoctoproject.org/docs/latest/bitbake-user-manual/bitbake-user-manual.html)
+
+To achieve a multiconfig build, a number of different config files need to
+be created in a single build directory.
+
+Create a new project
+----------------
+
+Before you start, you will need to follow the instructions in
+"Create a project" from the quickstart guide, to create a new project
+directory with
+  ```
+  oe-init-build-env my-mc-project
+  ```
+Ensure it has all the required layers in bblayers.conf as listed in
+`arm-autonomy-quickstart.md`. The result should be a directory containing:
+
+```
+-- conf
+ | -- bblayers.conf
+ | -- local.conf
+ | -- templateconf.cfg
+```
+
+Add multiconfig
+----------------
+
+Here are the steps required to make the project build both the host and any
+number of guests as required.
+
+1. Create a new directory under `conf/` named `multiconfig/`
+
+2. Create two new files in this directory:
+`multiconfig/host.conf`
+`multiconfig/guest.conf`
+These files will contain any configurations that a specific to either the
+host or the guest
+
+```
+-- conf
+ | -- bblayers.conf
+ | -- local.conf
+ | -- templateconf.cfg
+ | -- multiconfig
+    | -- host.conf
+    | -- guest.conf
+```
+
+3. In `local.conf` the following config variables must be added:
+
+```
+MACHINE ?= "fvp-base"
+
+# ---Guest Config Start--- #
+MC_GUEST = "guest"
+
+MC_GUEST_NAME = "guest1"
+
+MC_GUEST_IMAGERECIPE = "core-image-minimal"
+MC_GUEST_MACHINE = "arm64-autonomy-guest"
+
+MC_GUEST_INITRAMFS_IMAGE_BUNDLE ?= ""
+MC_GUEST_INITRAMFS_IMAGE ?= ""
+
+# Uncomment for initramfs
+#MC_GUEST_INITRAMFS_IMAGE_BUNDLE = "1"
+#MC_GUEST_INITRAMFS_IMAGE = "${MC_GUEST_IMAGERECIPE}"
+
+# These variables are set automatically, don't edit them!
+MC_GUEST_FILENAME_PREFIX = "${@ 'Image-initramfs' if d.getVar('MC_GUEST_INITRAMFS_IMAGE_BUNDLE',d) else '${MC_GUEST_IMAGERECIPE}' }"
+
+MC_GUEST_FILENAME = "${MC_GUEST_FILENAME_PREFIX}-${MC_GUEST_MACHINE}.xenguest"
+
+MC_GUEST_DEP = "${@ 'virtual/kernel:do_deploy' if d.getVar('MC_GUEST_INITRAMFS_IMAGE_BUNDLE',d) else '${MC_GUEST_IMAGERECIPE}:do_image_complete'}"
+
+MC_DOIMAGE_MCDEPENDS += "mc:${MC_HOST}:${MC_GUEST}:${MC_GUEST_DEP} "
+
+BBMULTICONFIG += "${MC_GUEST} "
+
+ARM_AUTONOMY_HOST_IMAGE_EXTERN_GUESTS += "file://${TOPDIR}/${MC_GUEST}/deploy/images/${MC_GUEST_MACHINE}/${MC_GUEST_FILENAME};guestname=${MC_GUEST_NAME} "
+# ---Guest Config End--- #
+
+# ---Host Config Start--- #
+MC_HOST = "host"
+
+BBMULTICONFIG += "${MC_HOST} "
+# ---Host Config End--- #
+```
+
+These variables will be used in both of the multiconf files. `MC_HOST` and
+`MC_GUEST` should not be altered without renaming the conf files, but most
+`MC_GUEST_*` variables can be customised if you desire.
+
+4. Next set the contents of `multiconfig/guest.conf`:
+
+```
+TMPDIR = "${TOPDIR}/${MC_GUEST}"
+
+MACHINE = "${MC_GUEST_MACHINE}"
+DISTRO_FEATURES += " arm-autonomy-guest"
+
+INITRAMFS_IMAGE_BUNDLE = "${MC_GUEST_INITRAMFS_IMAGE_BUNDLE}"
+INITRAMFS_IMAGE = "${MC_GUEST_INITRAMFS_IMAGE}"
+
+IMAGE_FSTYPES += "${@ 'cpio' if d.getVar('MC_GUEST_INITRAMFS_IMAGE_BUNDLE',d) else ''}"
+
+# ANY OTHER GUEST CONFIG
+```
+
+This contents shouldn't be changed directly, rather change the equivalent
+config in local.conf. You can append any other config desired for the
+guest at this point, for example `XENGUEST_IMAGE_DISK_SIZE`
+
+Make sure not to change `${DEPLOY_DIR_IMAGE}` to anything other than
+`${TMPDIR}/deploy/images`, as this is assumed by local.conf.
+
+5. Lastly set the contents of `multiconfig/host.conf`:
+
+```
+TMPDIR = "${TOPDIR}/${MC_HOST}"
+
+DISTRO_FEATURES += " arm-autonomy-host"
+```
+
+Building the image
+----------------
+
+To build the multiconfig image the command is:
+```
+bitbake mc:host:arm-autonomy-host-image-minimal
+```
+
+You should see that this triggers guest tasks to be built in
+parallel. Once the build completes the guest will already be in the
+rootfs of the host thanks to `ARM_AUTONOMY_HOST_IMAGE_EXTERN_GUEST`
+
+The deployed image including the guest will be in `host/deploy/images/`
+
+
+Multiple Guests
+----------------
+
+To have multiple guests with the same config the line which appends to
+`ARM_AUTONOMY_HOST_IMAGE_EXTERN_GUEST` just needs to be duplicated with
+a different guestname.
+
+To have different config for each guest, each will need its own config
+file similar to guest.conf, ensuring TMPDIR is set to a different path,
+and everything between `---Guest Config Start---` and
+`---Guest Config End---` will need to be duplicated.
+
+Any copies of variables that start `MC_GUEST` must be altered to avoid
+collisions (e.g. `MC_GUEST_2_*`), and the name of the conf file must also
+be added to BBMULTICONFIG.
+
+
+Guest with provisioned disk
+----------------
+
+To add guest rootfs partition to host wic image,
+set `AUTONOMY_HOST_EXTRA_PARTITION` with proper wks partition entry, e.g:
+
+```
+AUTONOMY_HOST_EXTRA_PARTITION = "part --label provisioned-guest --source rawcopy --fstype=ext4 --ondisk sda --align 1024 \
+--sourceparams=file=${TOPDIR}/${MC_GUEST}/deploy/images/${MC_GUEST_MACHINE}/${MC_GUEST_FILENAME_PREFIX}-${MC_GUEST_MACHINE}.ext4"
+```
+
+inside host.conf file.
+
+The rest of the configuration has to be appended to guest.conf file:
+
+```
+XENGUEST_IMAGE_DISK_SIZE = "0"
+XENGUEST_IMAGE_SRC_URI_XEN_CONFIG = "file://\${TOPDIR}/path/to/rootdisk.cfg"
+XENGUEST_IMAGE_DISK_DEVICE = "_GUEST_DISK_DEVICE_"
+XENGUEST_IMAGE_ROOT = "/dev/xvda"
+IMAGE_ROOTFS_SIZE = "102400"
+IMAGE_FSTYPES = "ext4"
+```
+
+content of rootdisk.cfg"
+
+```
+disk = ["phy:_GUEST_DISK_DEVICE_,xvda,w"]
+```
+
+`_GUEST_DISK_DEVICE_` should be substituted with `/dev/sdaX`,
+according to wks file.

+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-arm/meta-arm $LAYERDIR_BASE/meta-arm/meta-arm-toolchain \
+   $LAYERDIR_BASE/meta-arm/meta-arm-bsp $LAYERDIR_BASE/meta-arm/meta-arm-autonomy \
+  ```
+
+  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 \
+    /home/user/arm-autonomy/meta-arm/meta-arm-toolchain \
+    /home/user/arm-autonomy/meta-arm/meta-arm-bsp \
+    /home/user/arm-autonomy/meta-arm/meta-arm-autonomy \
+    "
+  ```
+
+  Be aware that changing the order may break some dependencies if editing the
+  config file manually.
+
+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.
+
+For arm-autonomy host on FVP-Base u-boot has been modified such that
+`booti 0x84000000 - 0x83000000` is the default boot command. If FVP-Base is your
+MACHINE target there should be no need to interfere with u-boot.
+
+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.
+
+The guest can also be built as a 'multiconfig' sub project of the host, see
+`meta-arm-autonomy/documentation/arm-autonomy-multiconfig.md` for more information
+
+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.

+Customizing Arm Autonomy Host image layout for N1SDP
+====================================================
+
+When buiding with `DISTRO_FEATURES += "arm-autonomy-host"` the user can
+perform a couple of customizations in the generated wic image:
+
+1. Set the guest partition size (default: 4iG) via `GUEST_PART_SIZE` and
+   `GUEST_PART_SIZE_UNIT` (M or G) variables to be set in any conf file. The
+   value of these variables should be aligned with the sum of all
+   XENGUEST_IMAGE_DISK_SIZE set for the guests. By default, LVM2 metadata is
+   1 MiB per physical volume, hence it needs to be taken into account when
+   setting GUEST_PART_SIZE.
+
+2. The wic image partition layout and contents with a custom wks file via
+   `ARM_AUTONOMY_WKS_FILE` variable (default:
+   arm-autonomy-n1sdp-efidisk.wks.in which is affected by GUEST_PART_SIZE,
+   GUEST_PART_SIZE_UNIT and GRUB_CFG_FILE variables).
+
+3. Custom grub.cfg file via `GRUB_CFG_FILE` (default:
+   arm-autonomy-n1sdp-grub.cfg) variable to be set in any conf file. The full
+   path or relative to `ARM_AUTONOMY_WKS_FILE` should be set.
+
+The `arm-autonomy-n1sdp-efidisk.wks.in` and `arm-autonomy-n1sdp-grub.cfg` files
+are located at `meta-arm-autonomy/dynamic-layers/meta-arm-bsp/wic`.
+
+Other variables can also be custmized to set what files need to be included
+in the wic image boot partition. Please refer to
+`meta-arm-autonomy/dynamic-layers/meta-arm-bsp/conf/machine/n1sdp-extra-settings.inc`
+for more details.
