arm-autonomy/u-boot: Modified kernel_addr for fvp-base with xen

Modified the default booti command for fvp-base with xen to boot into xen at 0x84000000, rather than requiring the user to break into the u-boot prompt.

-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

-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.

-Xenguest Network
-================
-
-Introduction
------------
-
-The xenguest-network package is primarly creating a network bridge to share
-the host eth physical interfaces with the guests virtual interfaces (vif).
-This way the guests can have access to the external network.
-
-At the moment 3 types of network arrangements are provided:
-
- Bridge: where the guest vif is added to the created bridge interface;
-
- NAT: where a private subnet is created for the guest,
-  a kea dhcp4 server is started on the host to serve the guest
-  and the proper iptables rules are created
-  to allow the guest to access the external network;
-
- None: the guest vif is not connected to the bridge.
-
-Usage
-----
-
-On the host project the package xenguest-network must be included in your
-image, and on the guest project the XENGUEST_NETWORK_TYPE needs to be set to
-"bridge", "nat" or "none".
-
-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
-or xenguest-network.bbappend, 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 the
-  physical network interfaces that are added to the bridge when it is created
-  on the host during init.
-  By default no physical interfaces are added.
-
- 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_TYPE: This variable can be set to "bridge" (default),
-  "nat" or "none".
-  The **bridge** type will add the domU vif interface to a bridge which also
-  contains the dom0 physical interface giving the guest direct access to the
-  external network.
-  The **nat** type will setup a private network between dom0 and domU, setup
-  the appropriate routing table, configure and run the kea dhcp4 server
-  on dom0 to serve the domU and apply the iptables rules to allow the guest
-  to acess the external network. The kea dhcp4 server configuration for
-  the guest can be customised by replacing the
-  "meta-arm-autonomy/recipes-extended/xenguest/files/kea-subnet4.json" file
-  in a xenguest-network.bbappend. The kea-subnet4.json file is installed in
-  the xenguest image and copied to
-  "/etc/xenguest/guests/${guestname}/files/kea-subnet4.json" when the guest
-  image is created. It will be consumed by the
-  "/etc/xen/scripts/vif-post.d/00-vif-xenguest.hook" script which is called by
-  "/etc/xen/scripts/vif-nat" script when starting/stopping the xenguest.
-  After guest start, "/etc/xenguest/init.post/xenguest-network-init-post.sh"
-  script is called to reload kea dhcp4 server with updated configuration,
-  after virtual network interface is ready.
-  In the guest project, the NAT port forward can be customised by changing
-  the XENGUEST_IMAGE_HOST_PORT (default: "1000 + ${domid}") and
-  XENGUEST_IMAGE_GUEST_PORT (default: "22") variables in local.conf or
-  xenguest-base-image.bbappend. This configuration is implemented and installed
-  in "/etc/xenguest/guests/${guestname}/files/00-xenguest-nat-port-forward.hook"
-  script which is called by "/etc/xen/scripts/vif-post.d/00-vif-xenguest.hook".
-  The **none** type will not affect any networking setting between on dom0 and
-  domU.

-arm-bsp/firmware-image-juno: add xen support
-
-This patch adds xen and dtbs binaries entries to images-r[012].txt files.
-These images-r[012].txt files contain NOR filesystem entries details,
-like file offset, name, path etc.
-
-It also adds customization for uEnv.txt file, that allows to autoboot xen.

+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.

-Subject: [PATCH] xen: use handle_fasteoi_irq to handle xen dynamic events
-
-When handling Xen events, we need to make sure the following sequence is
-followed:
-
- mask event
- handle event and clear event (the order does not matter)
- unmask event
-
-It is not possible to implement this flow with handle_edge_irq, so
-switch back to handle_fasteoi_irq. Please note that Xen event irqs are
-ONESHOT. Also note that handle_fasteoi_irq was in-use before the
-following commit, that is partially reverted by this patch:
-
-7e186bdd0098 xen: do not clear and mask evtchns in __xen_evtchn_do_upcall
-
-PIRQ handling is left unchanged.
-
-This patch fixes a domU hang observed when using LinuxRT as dom0 kernel.

-Subject: [PATCH] xen/arm: Missing N1/A76/A75 FP registers in vCPU context
- switch
-
-Xen has cpu_has_fp/cpu_has_simd to detect whether the CPU supports
-FP/SIMD or not. But currently, these two MACROs only consider value 0
-of ID_AA64PFR0_EL1.FP/SIMD as FP/SIMD features enabled. But for CPUs
-that support FP/SIMD and half-precision floating-point arithmetic, the
-ID_AA64PFR0_EL1.FP/SIMD are 1 (see Arm ARM DDI0487F.b, D13.2.64).
-For these CPUs, xen will treat them as no FP/SIMD support, the
-vfp_save/restore_state will not take effect.
-
-From the TRM documents of Cortex-A75/A76/N1, we know these CPUs support
-basic Advanced SIMD/FP and half-precision floating-point arithmetic. In
-this case, on N1/A76/A75 platforms, Xen will always miss the floating
-pointer registers save/restore. If different vCPUs are running on the
-same pCPU, the floating pointer registers will be corrupted randomly.
-
-This patch fixes Xen on these new cores.

-Subject: [PATCH] xen/arm: Throw messages for unknown FP/SIMD implement ID
-
-Arm ID_AA64PFR0_EL1 register provides two fields to describe CPU
-FP/SIMD implementations. Currently, we exactly know the meaning of
-0x0, 0x1 and 0xf of these fields. Xen treats value < 8 as FP/SIMD
-features presented. If there is a value 0x2 bumped in the future,
-Xen behaviors for value <= 0x1 can also take effect. But what Xen
-done for value <= 0x1 may not always cover new value 0x2 required.
-We throw these messages to break the silence when Xen detected
-unknown FP/SIMD IDs to notice user to check.
