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> Reviewed-by: York Sun <yorksun@freescale.com>
