Subject: [PATCH 0/2] MdePkg: add AARCH64 support to BaseMemoryLib
Date: Fri, 2 Sep 2016 12:40:35 +0100 [thread overview]
Message-ID: <1472816437-4525-1-git-send-email-ard.biesheuvel@linaro.org> (raw)
Now that ArmPkg's BaseMemoryLib implementation is broken due to upstream
API changes, now is a good time to move to the MdePkg versions.
So add AARCH64 support to both BaseMemoryLib (generic C) and
BaseMemoryLibOptDxe (accelerated). The former can be used anywhere, the
latter only in places where the caches are guaranteed to be on, not only
due to the unaligned accesses but also due to the fact that it uses
DC ZVA instructions for clearing memory.

MdePkg/BaseMemoryLib: widen aligned accesses to 32 or 64 bits
