Bug description:
[IMPACT]
* kexec-tools in Xenial (16.04) currently does not support ARM64
architecture.
* Backport support for ARM64 arch from upstream
https://github.com/horms/kexec-tools
* Majority of the patches are contained in kexec/arch/arm64/ except for
one patch that impacts purgatory and common device tree routines.
[TEST CASE]
* I built kexec-tools for ARM64 and tested it on HW using the following
testcase:
$ sudo kexec -l /boot/vmlinuz-<version>-generic
--initrd=/boot/initrd.img-<version>-generic
--command-line="root=UUID=<uuid> ro vt.handoff=7"
$ sudo kexec -e
* I was able to kexec the new kernel successfully.
* [ 6702.357899] kexec_core: Starting new kernel
[ 0.000000] Booting Linux on physical CPU 0x200
[ 0.000000] Linux version <version>-generic (buildd@bos01-arm64-008)
(gcc version 5.4.0 20160609 (Ubuntu/Linaro 5.4.0-6ubuntu1~16.04.4) )
[ 0.000000] Boot CPU: AArch64 Processor [510f8000]
[REGRESSION POTENTIAL]
* Since patches are confined to arm[64] there is a low overall risk of
regression.
[OTHER INFO]
* You can find a Xenial kexec-tools package built for AMD64, i386 and
ARM64 in my PPA
https://launchpad.net/~manjo/+archive/ubuntu/kexec-tools
* This package is built using the Xenial source package for kexec-tools
with ARM64 enablement patches applied.
* Please pull the changes from my PPA package and integrate into Ubuntu
Xenial kexec-tools after review.
