[U-Boot] [PATCH v3 2/2] powerpc/c29xpcie: 8k page size NAND boot support base on TPL/SPL
Po Liu
Po.Liu at freescale.com
Sat Dec 14 04:08:53 CET 2013
Using the TPL/SPL method to booting from 8k page NAND flash.
- Add 256kB size SRAM tlb for second step booting;
- Add spl.c for TPL image boot;
- Add spl_minimal.c for minimal SPL image;
- Add C29XPCIE_NAND configure;
- Modify C29XPCIE.h for nand config and enviroment;
Signed-off-by: Po Liu <Po.Liu at freescale.com>
---
changes for v2:
- seperate the public code and c29xpcie board code;
changes for v3:
- booting log simple to "SPL" "TPL"
- remove the 8k TLB from 0xffffe000 to 0xffffffff
- change the ddr tlb mapping condition
