driver/mtd:IFC NAND:Initialise internal SRAM before any write IFC-1.1.0 uses 28nm techenology for SRAM. This tech has known limitaion for SRAM i.e. "byte select" is not supported. Hence Read Modify Write is implemented in IFC for any "system side write" into sram buffer. Reading an uninitialized memory results in ECC Error from sram wrapper. Hence we must initialize/prefill SRAM buffer by any data before writing anything in SRAM from system side. To initialize SRAM user can use "READID" NAND command with read bytes equal to SRAM size. It will be a one time activity post boot.
