When ECC is enabled in DDR initialization, boot time is increased by almost a sec. This seems to be happening because the entire 2GB DDR is primed with a value in below code snippet. This requires optimization.

/* Prime memory with known pattern */
for (memPtr = BOARD_DDR_START_ADDR; memPtr < BOARD_DDR_ECC_END_ADDR; memPtr += 4)

{ *((volatile uint32_t *) memPtr) = memPtr; }
