Matt Fleming posted a 40-part (!) patch, with the queue of UEFI changes for Linux 4.7 kernel. Edited version of Matt’s part0 comments follow:
Folks, here’s the queue of EFI material for v4.7. This is probably the biggest EFI pull ever sent, and there quite a few different topics covered. On the plus side the majority of new features (EFI Memory Attribute tables, EFI capsules, GOP framebuffer) are basically architecture independent, and some of the existing architecture-specific code has been generalised and moved to drivers/firmware/efi.
* Drop the unused EFI_SYSTEM_TABLES efi.flags bit and ensure the ARM/arm64 EFI System Table mapping is read-only
* Add a comment to explain that one of the code paths in the x86/pat code is only executed for EFI boot
* Improve Secure Boot status checks on arm64 and handle unexpected errors
* Remove the global EFI memory map variable ‘memmap’ as the same information is already available in efi::memmap
* EFI Memory Attribute table support for ARM/arm64
* EFI GOP framebuffer support for ARM/arm64
* EFI Bootloader Control driver for storing reboot(2) data in EFI variables for consumption by bootloaders
* Core EFI capsule support
* EFI capsule char driver
* EFI memory map code unification for ARM and arm64
* Add generic EFI support for detecting when firmware corrupts cpu status register bits (like IRQ flags) when performing EFI runtime service calls
Ard Biesheuvel (19):
efi: Get rid of EFI_SYSTEM_TABLES status bit
efi/arm*: Drop writable mapping of the UEFI System table
efi: Check EFI_MEMORY_DESCRIPTOR version explicitly
efi/arm*: Use memremap() to create the persistent memmap mapping
ARM: efi: Apply strict permissons for UEFI Runtime Services regions
arm64: efi: Apply strict permissons for UEFI Runtime Services regions
efi: Add support for the EFI_MEMORY_ATTRIBUTES_TABLE config table
efi: Implement generic support for the Memory Attributes table
efi/arm*: Take the Memory Attributes table into account
x86/efi: Prepare GOP handling code for reuse as generic code
efi/libstub: Move Graphics Output Protocol handling to generic code
x86/efi: efifb: Move DMI based quirks handling out of generic code
efifb: Use builtin_platform_driver and drop unused includes
arm64/efi: libstub: Make screen_info accessible to the UEFI stub
efi/arm: libstub: Make screen_info accessible to the UEFI stub
efi/arm*: libstub: Wire up GOP protocol to struct screen_info
efi/arm*: Wire up struct screen_info to efi-framebuffer platform device
efifb: Enable the efi-framebuffer platform driver for ARM and arm64
efi/arm-init: Reserve rather than unmap the memory map for ARM as well
