[PATCH edk2-platforms v1 0/1] Use BaseMemoryLibMmio with NorFlashDxe

["Sami Mujawar" <sami.mujawar@arm.com>]

NorFlashDxe must use aligned MMIO accesses to
read data from flash as this is device memory.

The AlignedCopyMem() in NorFlashDxe was used to
copy the flash data which prevented unaligned
access to device memory. However, the compiler
could optimize the code to generate pre/post
indexed or LDP operations. This is a problem
for guest/virtual firmware as the hypervisor
code cannot get the syndrome information for
the trapped accesses.

With the introduction of virtual firmware
support for Kvmtool guests, it is necessary
to link NorFlashDxe with BaseMemoryLibMmio
(as it enforces aligned MMIO accesses).

This patch series updates the workspaces
for platforms that use the NorFlashDxe to
link with BaseMemoryLibMmio.

This patch series is dependent on the edk2
patch series that implements BaseMemoryLibMmio
and can be seen at:
