This is a followup to the single patch I sent out yesterday. Of course, it
was just the tip of the iceberg, and you know what happens when you make a
clean spot :-)
Anyway, this is a first pass at cleaning up the cache maintenance in the
various ARM packages.
Patch #1 is Mark Rutland's patch he sent out yesterday as well, I only
cleaned up the commitlog to refer to ArmPkg rather than ArmVirtPkg, and
mention AArch64 explicitly.
Patch #2 fixes a typo 'ArmDataSyncronizationBarrier' across all the
packages where it occurred.
Patch #3 removes the ARM9 version of ArmLib. There are no users, nor are
there likely to be new ones since ARM9 is so old.
Patch #4 removes the 'clean to PoU by set/way' routines.
Patch #5 removes the ARM_CACHE_INFO routines that mostly infer cache geometry
from CCSIDR which is explicitly forbidden by the architecture. Since there are
no users anyway, I just removed all of it.
Patch #6 fixes another illegal use of CCSIDR: cache maintenance by virtual
address needs to use the stride reported in CTR not CCSIDR
Patch #7 is based on the patch 'ArmPkg/ArmLib: remove pointless sync barriers
after each cache op' I sent out yesterday. As Mark Rutland and Leif pointed out,
the MVA outer loop (unlike the set/way outer loop) did not have the barriers yet
at the end, so this version adds those as well, and updates the ARMv7 side too.
Patch #8 updates the ArmCacheMaintenanceLib whole-cache maintenance routines to
ASSERT() rather than silently invoke the data cache maintenance by set/way
routines which we know are not appropriate at runtime.
Patch #9 and #10 remove some other uses of ArmInvalidateDataCache() at startup
time which are not appropriate at the UEFI firmware level.
