Merge tag 'signed-efi-next' of git://github.com/agraf/u-boot
Patch queue for efi - 2016-10-19
Highlights this time around:
- Add run time service (power control) support for PSCI (fixed in v3)
- Add efi gop pointer exposure
- SMBIOS support for EFI (on ARM)
- efi pool memory unmap support (needed for 4.8)
- initial x86 efi payload support (fixed up in v2)
- various bug fixes

+ Most armv8 systems have PSCI support enabled in EL3, either through
+ ARM Trusted Firmware or other firmware.
+
+ On these systems, we do not need to implement system reset manually,
+ but can instead rely on higher level firmware to deal with it.
