[GIT PULL 00/33] EFI updates for v5.8

[Ard Biesheuvel]

Hello Ingo, Thomas,

Please pull the attached changes into tip/efi/next. There is some
coordination going on with the RISC-V tree this time, so please take the
patches in this exact order, and apply them onto v5.7-rc2 so the first
three patches can serve as a shared stable base between the efi/core
branch and the riscv tree.

The following changes since commit ae83d0b416db002fe95601e7f97f64b59514d936:

  Linux 5.7-rc2 (2020-04-19 14:35:30 -0700)

  efi: Move arch_tables check to caller (2020-04-24 14:52:16 +0200)

----------------------------------------------------------------
EFI changes for v5.8:
- 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
