To follow up on this one, it additionally appears that commit
719e284369d23c3feb02d02ad58b3a516df47806 [1] was premature, as ARM
support for EFI never fully made it into mainline, and the files
referenced[2] do not exist anywhere in the history.

Umm.. actually could you resend this with your Signed-off-by tag,
please? Then I'll apply it.

Thanks, applied for v4.5.
