31530e0b8a board/t104xrdb: Conditional workaround of errata A-008044
Workaround of Errata A-008044 was implemented without errata number and it is
enabled by default. Errata A-008044 is only valid for T1040 Rev 1.0.

So put errata number and make it conditional.

9f074e67f5 powerpc/mpc85xx:Put errata number for T104x NAND boot issue
When device is configured to load RCW from NAND flash IFC_A[16:31] are driven
low after RCW loading. Hence Devices connected on IFC_CS[1:7] and using
IFC_A[16:31] lines are not accessible.

Workaround is already in-place.
Put the errata number to adhere errata handling framework.

ce249d956c powerpc/t104xrdb: support deep sleep in SPI/SD boot
Add deep sleep support in SPI/SD boot. The destination address
second stage uboot image is loaded to is changed because
currently this address will be used by kernel which means
we can't reserve it for resume.

Entry point to kernel is still placed in second stage uboot.

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
