Yesterday's patch is now a 3-piece series, since I spotted some other issues
when looking at this code.
Patch #1 replaces the bogus TTBR_WRITE_THROUGH_NO_ALLOC with something that is
more aligned with what TTBRx actually allows.
Patch #2 adds the shareable bit to the TTBR config to ensure that page table
accesses to cached memory are shareable.
Patch #3 is yesterday's patch, updated with Leif's R-b, and an additional
override of the shareable bit added in patch #2
Ard Biesheuvel (3):
ArmPkg/ArmV7Mmu: fix write-through translation table accesses
ArmPkg/ArmV7Mmu: make cached translation table accesses shareable
ArmPkg/ArmV7Mmu: introduce feature PCD to map normal memory
non-shareable
