[PATCH 2/3] automation: Add arm{64,32} earlyprintk jobs

[Michal Orzel <michal.orzel@xxxxxxx>]

Introduce qemu based Arm earlyprintk test and build jobs to cover this
feature in debug variant. The tests simply check for the presence of the
last message printed by the bootstrap code before entering the C world.
