board/t104xrdb: Add support of NAND, SD, SPI boot for T104xRDB Add support of 2 stage NAND, SD, SPI boot loader using SPL framework. here, PBL initialise the internal SRAM and copy SPL(160KB). This further initialise DDR using SPD and environment and copy u-boot(768 KB) from NAND to DDR. Finally SPL transer control to u-boot. Initialise/create followings required for SPL framework - Add spl.c which defines board_init_f, board_init_r - update tlb and ddr accordingly Signed-off-by: Prabhakar Kushwaha <prabhakar@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>

#PBI commands
t104xrdb: Add Errata A_007662, A_008007 workaround in pbi.cfg -A_007662 states that for x1 link width, PCIe2 controller trains in Gen1 speed while configured for Gen2 speed. Workaround:Set the width to x1 and speed to Gen2 by writing to CCSR registers in PBI phase -A_008007 states that PVR register may show random value. Workaround: Reset PVR register using DCSR space in PBI phase Add PBI based software workaround for A_007662 and A_008007 in t104x_pbi.cfg. This is required for SPL-based bootloaders like NAND-boot, SD-boot, SPI-boot Signed-off-by: Priyanka Jain <Priyanka.Jain@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
