driver/mtd:IFC NAND:Initialise internal SRAM before any write 2012-11-26T21:41:28+00:00 Prabhakar Kushwaha prabhakar@freescale.com 2012-09-12T22:26:05+00:00 79da5e3d5d6be28d1c82265bbeb0ff4633fc5535 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 Signed-off-by: Prabhakar Kushwaha <prabhakar@freescale.com> [scottwood@freescale.com: fix fsl_ifc_sram_init prototype] Signed-off-by: Scott Wood <scottwood@freescale.com>
