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"
