Hi, 
This is v6 of [1] 

Changes since V5:
 - Addressed coding style fixes from Pierre
 - Removed redundant checks in memory allocation and block usage
 - Removed unused COMPRESSION_TOOL_GUID
 - Renamed the files and directories following Leif's sugestion
 - Added Sami and myself as maintainers

Changes since V4:
 - More coding stule fixes proposed by Sami, which Ecc or Patchcheck didn't
   report.
 - Adding missing error handling in InitializeFvAndVariableStoreHeaders().
   An allocation wasn't properly checked for success

Changes since V3:
 - Coding style fixes proposed by Sami
 - Fixed all reported PatchCheck errors
 - Added overflow checks on the base aaddress allocated for EFI variables.
   The size of the partition is user defined (via Pcd's) and the memory layout
   and allocation address depends on OP-TEE. So let's make sure we won't overflow
   when calculating the 3 partitions needed for FTW
 - Switched some PcdGet/Set32 to 64 to accomodate 64-bit addressing
 - Removed some duplicate entries in Platform/StMMRpmb/PlatformStandaloneMm.dsc
 - Added reviewed-by tags on patch 2/2

Changes since V2:
 - Allocate a dynamic number of pages based on the Pcd values instead
   of a static number
 - Clean up unused structs in header file
 - Added checks in OpTeeRpmbFvbGetBlockSize and handle NumLba=0

Changes since V1:
Some enhancements made by Ilias to the Optee Rpmb driver
