[U-Boot] [PATCH v2] powerpc/t1040qds: Add support of SD boot for T1040QDS Board
Vijay Rai
vijay.rai at freescale.com
Fri Dec 19 13:35:48 CET 2014
Add support of 2 stage SD boot loader using SPL framework.
here, PBL initialise the internal SRAM and copy SPL(160KB). This further
initialise DDR using SPD 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
Add T1040QDS_SDCARD_defconfig
Update t1040_pbi.cfg to support errata A-007662, A-008007 and LAW for CPC1
Signed-off-by: Vijay Rai <vijay.rai at freescale.com>

changes from v1:
-Updated Kconfig to support SPL option for T1040QDS
