[U-Boot] [PATCH 7/7 v7] powerpc: p1022ds: add TPL for p1022ds nand boot

Tue Jul 9 11:50:50 CEST 2013


From: Ying Zhang <b40530 at freescale.com>

TPL is introduced in the patch "NAND: TPL : introduce the TPL
based on the SPL", here enable TPL for p1022ds nand boot.

Signed-off-by: Ying Zhang <b40530 at freescale.com>
---
Change from v6:
- Delete the file "board/freescale/p1022ds/tpl.c".
- Reuse the file "board/freescale/p1022ds/spl.c" in the TPL.
Change from v5:
- Change functionality nand_load_image to nand_load, it is called in TPL.
Change from v4:
- No change.
Change from v3:
- No change.
Change from v2:
- No change.
Change from v1:
- Split from "powerpc/p1022ds: nand: introduce the TPL based on the SPL".
