This patch provides enough implementation of the following protocols to
run EDKII's Shell.efi and UEFI SCT:
* EfiHiiDatabaseProtocol
* EfiHiiStringProtocol
Not implemented are:
* ExportPackageLists()
* RegisterPackageNotify()/UnregisterPackageNotify()
* SetKeyboardLayout() (i.e. *current* keyboard layout)
HII database protocol in this patch series can handle only:
* GUID package
* string package
* keyboard layout package
(The other packages, except Device path package, will be necessary
for interactive and graphical UI.)

Thanks, applied to efi-next

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.
I've posted a patch to remove only the protocol exposure. That way we
can leave most bits in.
The #SError sounds like something is trying to write to a memory
location that is not backed by a device. That is usually an indicator
for a NULL dereference. Maybe by looking at the respective iPXE code,
you will be able to find the spot that does the invalid access?
