Like I asked when this patch was sent round the last time: is there
any reason for this not to live in generic code?
It's interpreting the x86 boot_params at this point.  I suppose I could move
the following piece:

	if (efi_enabled(EFI_BOOT)) {
		switch (boot_params.secure_boot) {
		case efi_secureboot_mode_disabled:
			pr_info("Secure boot disabled\n");
			break;
		case efi_secureboot_mode_enabled:
			pr_info("Secure boot enabled\n");
			break;
		default:
			pr_info("Secure boot could not be determined\n");
			break;
		}
	}

into generic code and pass in boot_params.secure_boot as an argument (since
that's x86-specific I believe.  Any suggestions as to where?  The same file as
efi_get_secureboot() would seem to be the wrong place since that gets linked
into the bootwrapper.  I could put it into drivers/firmware/efi/secure_boot.c
and make that conditional in the Makefile.
