Hi EDK-2 Experts, 
I am looking to store NV variables on SD/NAND device. 

While browsing, I came across some old post at link, 
http://feishare.com/efimail/messages/20130319-1700-Re__edk2__Regarding_storing_Boot_Device_Config_in_persistent_memory-Olivier_Martin.html 

Looks like, this is possible easily. 
>> What you need to support Non-Volatile UEFI variables is a Non-Volatile Memory. And also a driver that implements the EFI Firmware Volume Block protocol for this NVM device.

But MdeModulePkg does Copymem from NV variable start memory to some allocated buffers.  With SD/NAND Copymem is not possible, Is this something changes since 2013 or there are some other way to use SD/NAND 

Thanks
Udit
