CI: pin to kas 3.2 as 3.2.1 fails

For some reason the kas 3.2.1 container fails: No such file or directory: '/builds/engineering/yocto/meta-arm/ci/ci/base.yml' Note the repeated /ci/, which is wrong. Pin the kas container to 3.2 for now until this is resolved. Signed-off-by: Ross Burton <ross.burton@arm.com>

-# 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       |
-| Internal Storage  | ts-its          |
-| Protected Storage | ts-storage      |
-| se-proxy          | ts-se-proxy     |
-| smm-gateway       | ts-smm-gateway  |
-| spm-test[1-3]     | 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-ffa-tee`.)
-
-   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.
-
-## 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 guest
+images.
+
+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)
+* meta-networking (git://git.openembedded.org/meta-openembedded)
+
+Distribution Features
+---------------------
+This layer adds the following Yocto DISTRO_FEATURES:
+
+* arm-autonomy-host: this feature activates functionalities required to build
+  an autonomy host system. It has the following effects:
+  - 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](documentation/xenguest-network.md)
+
+BSPs
+----
+This layer adds the following machine:
+
+* arm64-autonomy-guest: This machine 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 and xenguest images. This image depends on
+ 'arm-autonomy-host' distribution feature.
+
+Recipes and classes
+-------------------
+This layer adds 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 used to
+  create and modify images to be used as Xen guests.
+
+* [xenguest-manager](documentation/xenguest-manager.md): This is a tool used to
+  create/remove/start/stop xen guest generated using xenguest-mkimage.
+
+* [xenguest-network](documentation/xenguest-network.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.
+
+Contributing
+------------
+This project has not put in place a process for contributions currently. If you
+would like to contribute, please contact the maintainers

+#   - Note that a checksum (md5sum or sha256sum) must be provided for http(s)
+#
+# - file:// absolute local path from root
+#   - In this case the filename will be added to SRC_URI and the path from '/'
+#   added to FILESEXTRAPATHS
+#
+# - file:// path relative to FILESEXTRAPATHS
+#   - In this case the filename will be added to SRC_URI and the preceding path
+#   added to FILESOVERRIDES, so that the full path to the file will
+#   be available in FILESPATH when it is generated by combining
+#   FILESEXTRAPATHS and FILESOVERRIDES.
+#
+# - plain absolute local path from root
+#   - This will be treated the same as an file:// path from root. Plain paths
+#   must be absolute, and cannot be relative to FILESEXTRAPATHS
+#
+# It is not recommended to use other yocto URL types, as they may result in
+# undefined behaviour.
+#
+# These entries will be added to the SRC_URI so that the yocto fetcher can
+# unpack a copy into ${WORKDIR}/${SRC_URI_FROM_VAR_UNPACK_DIR}
+#
+#
+# A list of arguments can follow each entry in the input variable, seperated
+# by semi-colons (;). Arguments may be FETCH arguments or MANIFEST arguments.
+#
+# FETCH arguments will be appended to the entry in SRC_URI, for example
+# "downloadfilename" to specify the filename used when storing a
+# downloaded file.
+# Each SRC_URI entry will automatically have the arguments
+# "unpack=0;subdir=${SRC_URI_FROM_VAR_UNPACK_DIR}" added to them, so do not
+# attempt to set these options.
+#
+# MANIFEST arguments are defined in the variable
+# SRC_URI_FROM_VAR_MANIFEST_PARAMS which should be a space seperated list of
+# names, each optionally followed by an equals sign (=) and a default value.
+#
+# The values provided for the manifest arguments will be written to the manifest
