The "bootefi selftest" command works on qemu-x86_64 when $loadaddr is changed:
  => env set loadaddr 0x10000000

Another patch "x86: use EFI calling convention for efi_main on x86_64"
also needs to be applied.

The self test starts but crashes on 'manage protocols':

  Tearing down 'graphical output'
  Tearing down 'graphical output' succeeded

  Setting up 'manage protocols'


Same effect with a 64-bit build for Minnowboard.
