Author: emaste Date: Thu Apr 2 18:57:35 2015 New Revision: 281000 URL: https://svnweb.freebsd.org/changeset/base/281000 Log: Move i386/efi files to new home in efi/loader/arch/i386 This was not (and still is not) connected to the build, but the EFI loader is in the process of being built for other than amd64 so these files ought to live in their eventual MD location.
