The NullMemoryTestDxe and GenericMemoryTestDxe both have one function, which is switching the untested memory of type EfiGcdMemoryTypeReserved to EfiGcdMemoryTypeSystemMemory.
The above 4GB memory is not reported as system memory in UEFI memory map before BDS on hisilicon platforms. After running memory test protocol, whether it is from NullMemoryTestDxe or GenericMemoryTestDxe, memory space above 4GB will be switched to EfiGcdMemoryTypeSystemMemory and reported in UEFI memory map.
There are 8 DIMM slots at D03 platform, it takes about 2 minutes to do memory test when inserting full memory(16G*8), so we switch to NullMemoryTest to promote boot time.
