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

+	  ARM Trusted Firmware or other firmware.
+
+	  On these systems, we do not need to implement system reset manually,
