as SRAM

0921de6744 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

18c0144542 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
