Subject: Pstore : Query on using ramoops driver for DDR

Hi All,

Can we use existing backend pstore ram driver (fs/pstore/ram.c) for DDR 
instead of SRAM ?
Was the current driver written only to support persistant RAM like SRAM 
or it can accept further change
to support DDR, If we have a mechanism to copy stored data from DDR to 
external device after the crash.

Thanks,
Mukesh
