Subject: [edk2-devel] [PATCH RESEND edk2-platforms][PATCH V2 04/14] Platform/ARM/NorFlashDxe: Move flash specific functions to NorFlash.c
From: sahil <sahil@arm.com>
Refactoring done in this patch has two major parts:
1. Moving out NorFlashUnlockAndEraseSingleBlock and
NorFlashWriteFullBlock functions from NorFlashDxe.c and
NorFlashStandaloneMm.c to NorFlash.c files.
2. At the same time, we are adding NorFlashLock and NorFlashUnlock
functions which will take care of TPL related operations needed by
functions mentioned in point 1. These functions are implemented
in NorFlashDxe.c but are just dummy placeholder functions in
NorFlashStandaloneMm.c file.
