Using the TPL method for nand boot by sram was already supported. Here add some code for mpc85xx ifc nand boot.
- For ifc, elbc, esdhc, espi, all need the SPL without section .resetvec. - Use a clear function name for nand spl boot. - Add CONFIG_SPL_IFC_SUPPORT to compile the fsl_ifc.c in spl/Makefile;
Signed-off-by: Po Liu Po.Liu@freescale.com --- changes for v2: - seperate public code and c29xpcie board code - add ifc support changes for v3: - remove the redundant plus - ifc support use CONFIG_SPL_DRIVERS_MISC_SUPPORT
