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>

+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}"

+
+# 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.

-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] arm/arm64: xen: Fix to convert percpu address to gfn
+ correctly
+
+Use per_cpu_ptr_to_phys() instead of virt_to_phys() for per-cpu
+address conversion.
+
+In xen_starting_cpu(), per-cpu xen_vcpu_info address is converted
+to gfn by virt_to_gfn() macro. However, since the virt_to_gfn(v)
+assumes the given virtual address is in linear mapped kernel memory
+area, it can not convert the per-cpu memory if it is allocated on
+vmalloc area.
+
+This depends on CONFIG_NEED_PER_CPU_EMBED_FIRST_CHUNK.
+If it is enabled, the first chunk of percpu memory is linear mapped.
+In the other case, that is allocated from vmalloc area. Moreover,
+if the first chunk of percpu has run out until allocating
+xen_vcpu_info, it will be allocated on the 2nd chunk, which is
+based on kernel memory or vmalloc memory (depends on
+CONFIG_NEED_PER_CPU_KM).
+
+Without this fix and kernel configured to use vmalloc area for
+the percpu memory, the Dom0 kernel will fail to boot with following
+errors.

+Subject: [PATCH] arm/xen: Don't probe xenbus as part of an early initcall
+
+commit c4295ab0b485b8bc50d2264bcae2acd06f25caaf upstream.
+
+After Commit 3499ba8198cad ("xen: Fix event channel callback via
+INTX/GSI"), xenbus_probe() will be called too early on Arm. This will
+recent to a guest hang during boot.
+
+If the hang wasn't there, we would have ended up to call
+xenbus_probe() twice (the second time is in xenbus_probe_initcall()).
+
+We don't need to initialize xenbus_probe() early for Arm guest.
+Therefore, the call in xen_guest_init() is now removed.
+
+After this change, there is no more external caller for xenbus_probe().
+So the function is turned to a static one. Interestingly there were two
+prototypes for it.
+

+Fixes: 3499ba8198cad ("xen: Fix event channel callback via INTX/GSI")

 # N1SDP Development Platform Support in meta-arm-bsp

+## Overview
+The N1SDP provides access to the Arm Neoverse N1 SoC. The N1SDP enables software development for key enterprise technology
+and general Arm software development. The N1SDP consists of the N1 board containing the N1 SoC.
+The N1 SoC contains two dual-core Arm Neoverse N1 processor clusters.
+
+The system demonstrates Arm technology in the context of Cache-Coherent Interconnect for Accelerators (CCIX) protocol by:
+
+- Running coherent traffic between the N1 SoC and an accelerator card.
+- Coherent communication between two N1 SoCs.
+- Enabling development of CCIX-enabled FPGA accelerators.
+
+Further information on N1SDP can be found at
+https://community.arm.com/developer/tools-software/oss-platforms/w/docs/458/neoverse-n1-sdp

+Subject: [PATCH] Backport fix for PR/tree-optimization/97236 - fix bad use of
+ VMAT_CONTIGUOUS
+
+This avoids using VMAT_CONTIGUOUS with single-element interleaving
+when using V1mode vectors.  Instead keep VMAT_ELEMENTWISE but
+continue to avoid load-lanes and gathers.
+
+2020-10-01  Richard Biener  <rguenther@suse.de>
+
+	PR tree-optimization/97236
+	* tree-vect-stmts.c (get_group_load_store_type): Keep
+	VMAT_ELEMENTWISE for single-element vectors.
+
+	* gcc.dg/vect/pr97236.c: New testcase.
