[coreboot] Simple non-Linux payload for checking ARM devices (QEMU)

[Paul Menzel]

Dear coreboot folks,

Elyes is working on upgrading the coreboot crossgcc toolchain, 
especially to GCC 10.1.0, and wants to test the results with the QEMU 
emulation.

Unfortunately, for ARM devices – and probably all other non-x86 one – 
there seems to no simple payload to test with.

It was recommended to use a Linux payload, but as this of course should 
also be tested, is there an easy, maybe libpayload based, payload to test.

Can depthcharge be built easily with some kind of test menu to display 
the CBMEM console and timestamps and some test image for the framebuffer?

Has anybody looked, what makes coreinfo x86 specific?

Kind regards,

Paul
