[U-Boot] [PATCH] powerpc/t1040qds: Add support of SD boot for T1040QDS Board

Vijay Rai vijay.rai at freescale.com
Sat Nov 1 08:31:51 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
