Add basic support to run m68k under QEMU via kunit_tool. Signed-off-by: Geert Uytterhoeven <geert@xxxxxxxxxxxxxx> ---
Thanks very much. This works fine here. I'll look into failures for individual kunitconfigs and tests later, but the actual kunit_tool/QEMU stuff seems good-to-go to me. Reviewed-by: David Gow <davidgow@xxxxxxxxxx> Cheers, -- David
Does this need CONFIG_VIRTIO_CONSOLE=y? It seems to work fine without.
It's working fine here without, too, so _something_ must be sending data to the console.

It looks like there are some endianness issues with the apparmor policy_unpack_test, too... Otherwise the default set of tests seems to pass.
