Merge tag 'efi-next' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi into efi/core

Pull EFI changes for v5.8 from Ard Biesheuvel:

"- preliminary changes for RISC-V
 - add support for setting the resolution on the EFI framebuffer
 - simplify kernel image loading for arm64
 - Move .bss into .data via the linker script instead of relying on symbol
   annotations.
 - Get rid of __pure getters to access global variables
 - Clean up the config table matching arrays"
