IIUC, this is a requirement for Linux. Because when Linux parses the

See efi_get_fdt_params in drivers/firmware/efi/efi.c.
This is *not* a requirement for Linux. All those properties are internal
to Linux so it's not exposed to anyone else. We have room to change it
while we standardize the property.
