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 Signed-off-by: Tom Rini <trini@konsulko.com> Conflicts: include/tables_csum.h
