[U-Boot] [PATCH 1/4 v2] Add TPL and P1021MDS board support

Haiying.Wang at freescale.com Haiying.Wang at freescale.com
Mon Feb 7 22:14:13 CET 2011


From: Haiying Wang <Haiying.Wang at freescale.com>

This patch supports P1021MDS board to boot from NAND flash (No NOR flash on this
board). And because P1021 only has 256K L2 SRAM, which can not used for final
uboot image, this patch also introduces TPL(Tertiary Program loader) to enable a
loader stub that boots out of some type of RAM, after being loaded by an SPL or
similar platform-specific mechanism.

This patch enables the TPL BOOT on P1021MDS so that DDR can be initialized in L2
SRAM through SPD code. So there are three stage uboot images:
* nand_spl, pad from 4KB size to 16KB, load tpl_boot from offset 16KB in NAND.
* tpl_boot, 112KB size. The env variables are copied to offset 128KB
  in L2 SRAM, so that ddr spd code can get the interleaving mode setting in env.
  It loads final uboot image from offset 128KB in NAND.
* final uboot image, size is variable depends on the functions enabled.

README is updated by this patch to support TPL as well as NAND SPL boot.

v2: Move TPL common codes to this patch which calls them, move README to here.
make changes to board ddr.c and law.c based on the latest commits in u-boot-85xx
git tree, make change to board header file according to Wolfgang's comments.
