From: Priyanka Jain Priyanka.Jain@freescale.com
Using DDR as RAMBOOT base instead of L2SRAM for SDCard and SPI Flash boot loaders because: - P1_P2_RDB boards have soldered DDR so no need for SPD - Also P102x has 256K L2 cache size so becomes a limiting factor for size of image that could be loaded in SRAM mode and would require three stage boot loader (TPL).
Changes done: 1. CONFIG_SYS_TEXT_BASE to 0x11000000 2. CONFIG_RESET_VECTOR_ADDRESS to 0x1107fffc
