[PATCH 1/2] efi: payload: iomem: use efi_uintn_t for the memory map key

[Ahmad Fatoum]

The GetMemoryMap() boot service takes a pointer to an efi_uintn_t for
the map key. Passing a pointer to an unsigned long fails to compile on
32-bit architectures, where efi_uintn_t is 32-bit:

  efi/payload/iomem.c:161:45: error: passing argument 3 of
  'BS->get_memory_map' from incompatible pointer type

Use the correct type.
