Ard Biesheuvel 4dbe44fb53 efi: capsule: clean scatter-gather entries from the D-cache ... Scatter-gather lists passed to UpdateCapsule() should be cleaned from the D-cache to ensure that they are visible to the CPU after a warm reboot before the MMU is enabled. On ARM and arm64 systems, this implies a D-cache clean by virtual address to the point of coherency. However, due to the fact that the firmware itself is not able to map physical addresses back to virtual addresses when running under the OS, this must be done by the caller.
