[PATCH 00/10] Improve UEFI app support

[Matthew Garrett]

We run a mixed environment including traditional embedded Linux and 
UEFI. For consistency it's valuable to use U-Boot in both cases, but on 
UEFI systems we want to run the full Linux kernel UEFI boot stub. This 
patchset adds support for that, along with various other quality-of-life 
improvements such as automatically finding partitions based on their 
GUID, automatic identification of load addresses where the firmware has 
given us constraints, support for EFI variable access in the EFI app, 
drivers for EFI network adapters and TPMs, support for embedding DTBs in 
the EFI app, and a couple of bug fixes.
