Hi Dave,
I've applied this patch to uefi-next.git now. The branch "linaro-tracking" should have everything there, with an almost-up-to-date edk2 source.
I haven't tested Panda at all, other than built it, so if you want to give it a test asap (code freeze day is tomorrow) then please do and let me know.
Cheers, Ryan.

I did successfully build and boot uefi on my 4460. I'm not really set up to actually boot a linux kernel with uefi at the moment, which may be the reason it stopped with the following error:
The default boot selection will start in 1 seconds ASSERT /home/dave/nfsroot/junk/uefi-next/MdePkg/Library/UefiDevicePathLib/DevicePathUtilities.c(160): Length >= sizeof (EFI_DEVICE_PATH_PROTOCOL)
I was able to get into the UEFI shell and run assorted commands.

Yes, I'd expect you're right. So long as UEFI runs for the moment, that's
good enough for me. Ideally, it should boot the kernel happily, but actually having Panda run UEFI is great news!

Marvelous! Thanks for testing it.
