Hi all,

This series enabled qemu-xtensa board.

For dc232b CPU it needs to be built with toolchain[1].

This is a side product of me investigating architectures
physical address != virtual address in U-Boot. Now we can
get it covered under CI and regular tests.

VirtIO devices are not working as expected, due to U-Boot's
assumption on VA == PA everywhere, I'm going to get this fixed
later.

My Xtensa knowledge is pretty limited, Xtensa people please
feel free to point out if I got anything wrong.

Thanks
