Sorry, that is "-machine" instead of "-m", and the actual file you use
is "boot/bin/boot.bin", not "mimas_v2.bin".

Also, Qemu emulation is going pretty well now [1]. I'm
remote-debugging the boot rom. I actually had to disable
CONFIG_CPU_TESTS because otherwise I was getting stuck in _fail.

Now I'm getting into ddr_init(). Likely just some memory map issues.
to sort out.

Cheers,

C
