Subject: [efi] Default to using raw x86 I/O
X-Git-Tag: v1.20.1~1708
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2d7c966e77f504dc9b53f6d18a2f01deb7b9cb4a;p=thirdparty%2Fipxe.git

[efi] Default to using raw x86 I/O

The EFI_CPU_IO_PROTOCOL is not available on all EFI platforms.  In
particular, it is not available under OVMF, as used for qemu.

Since the EFI_CPU_IO_PROTOCOL is an abomination of unnecessary
complexity, banish it and use raw I/O instead.
