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

powerpc/mpc85xx/p2020rdb-pca: Use L2 SRAM for SPL boot
This allows DDR configuration to be deferred to the final U-Boot image,
which is able to make use of SPD data. The SPL itself cannot use SPD due
to code size constraints. It previously used fixed register values for
DDR configuration, and those values did not work on the p2020rdb-pca
board I tested with. It's possible that different revisions of the board
require different settings. Using SPD eliminates that problem.
