This is a combined set of patches for the arm and arm64 kernel
support for UEFI firmware.
The set depends on the following prerequisite sets:
- Laura Abbott's 'Remove ARM meminfo'
- Matt Fleming's 'Move facility flags to struct efi'
- Mark Salter's 'Generic fixmap'
- Mark Salter's 'Generic

Loading unauthenticated FDT blobs directly from storage is a security hazard,
so this should only be allowed when running with UEFI Secure Boot disabled.

This patch adds EFI stub support for the ARM Linux kernel. The EFI stub
operates similarly to the x86 stub: it is a shim between the EFI firmware
and the normal zImage entry point, and sets up the environment that the
zImage is expecting. This includes

The ARM decompressor/EFI stub do not implement the functions
(__stack_chk_guard_setup, etc) that are required for support of
stack protection. The actual enablement of stack protection is
controlled by heuristics in GCC, which the code added for the EFI

At boot time, before switching to a virtual UEFI memory map, firmware
expects UEFI memory and IO regions to be identity mapped whenever
kernel makes runtime services calls. The exisitng early boot code
creates an identity map of kernel text/data but this is
Since the efi_set_virtual_address_map call has strict init ordering
requirements, add an explicit hook in the required place.

This patch adds the EFI stub entry point that is shared
by the arm/arm64 architectures. Each arch will implement
the handle_kernel_image() function that handles the arch

The shared efi-stub-helper.c functions require a strstr implementation.
The EFI stub is part of the decompressor, so it does not use the kernel
strstr() implementation. This patch adds a strstr() implementation to
the string.c file for the decompressor, with

This patch implements basic support for UEFI runtime services in the
ARM architecture - a requirement for using efibootmgr to read and update
the system boot configuration.
It uses the generic configuration table scanning to populate ACPI and
SMBIOS pointers.

Both ARM and ARM64 stubs will update the device tree that they pass to
the kernel. In both cases they primarily need to add the same UEFI
related information, so the function can be shared. Create a new FDT
related file for this to avoid use of architecture
