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" Signed-off-by: Ingo Molnar <mingo@kernel.org>
