2014-07-09ArmPkg/ArmLib: Improved ArmConfigureMmu PerformanceEugene Cohen
Data & Instruction Caches can be kept enabled while the new translation table is filled. Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Eugene Cohen <eugene@hp.com> Reviewed-By: Olivier Martin <olivier.martin@arm.com> git-svn-id: https://svn.code.sf.net/p/edk2/code/trunk/edk2@15647 6f19259b-4bc3-4df7-8a09-765794883524
2014-06-03ArmPkg/ArmLib: Drain Write Buffer before DCache maintenance operations.Olivier Martin
Cache maintenance operations by Set/Way require that the Write Buffer be drained before the cache is flushed. Without that, the flush can miss the most recent values written as they are still "pipelined". That has unfortunate consequences, especially where code is being copied to RAM. The fix is to add DSB instructions before the affected operations.

2014-03-01ArmPkg/ArmLib: Rationalise ArmReadMidr and cognate functions.Olivier Martin
The function ArmReadMidr has been recently added, but that functionality was already present under other names such as Cp15IdCode and ArmMainIdCode. This change removes redundant code and moves the function to the Common library.
