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_DRIVERS_MISC_SUPPORT to compile the fsl_ifc.c in spl/Makefile; Signed-off-by: Po Liu <Po.Liu@freescale.com> Acked-by: Scott Wood <scottwood@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
