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@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
