So, this is trying to allocate (any) memory below 4GB and succeeds the first
time, but, not the second...

- What does the memory map look like?

- Is there sufficient memory left below 4GB, or is all the memory mapped above
  4GB on this board?

- What happens if you change AllocateMaxAddress to AllocateAnyPages in
  efi_md_init()?
