[PATCH v2 1/2] automation: Add support for using XTF for arm64 testing
Posted by Michal Orzel 3 years, 1 month ago 
Introduce support for using XTF on Arm to perform low-level testing.
For the purpose of the CI testing, let's use the fork [1] from upstream
XTF with implemented support for arm64 (the upstream XTF only supports
x86).

Add a new script under automation/scripts to be used by the CI XTF test
jobs to perform the following tasks:
 - Compiling XTF,
 - Generating u-boot script using ImageBuilder,
 - Running Xen with XTF as domU in pure dom0less configuration using Qemu,
 - Checking test result.

The script takes the name of the XTF test to run as a first parameter.
