I have rebased the efi-next tree upon U-Boot master. My Odroid C2
crashes when booting via U-Boot -> iPXE -> GRUB -> Linux. Bisection
points to this patch. The HII protocols are referenced by iPXE if available.

An interesting comment in
https://www.spinics.net/lists/arm-kernel/msg704238.html for a similar
U-Boot related error is:

"Looks like you're taking the SError as soon as we unmask them, so it
could've been pending for ages. It would be interesting to see if it's
actually caused by the kernel, or if the firmware triggers it beforehand."

Booting via iPXE is described in doc/README.iscsi

This patch and some follow up patches are included in the pull request
for the EFI tree.

I would prefer if we could remove the HII protocols from the pull
request until the patches are thoroughly tested.
