CONFIG_SPL_FAT_LOAD_PAYLOAD_NAME
Filename to read to load U-Boot when reading from FAT
+ CONFIG_SPL_MPC83XX_WAIT_FOR_NAND
+ Set this for NAND SPL on PPC mpc83xx targets, so that
+ start.S waits for the rest of the SPL to load before
+ continuing (the hardware starts execution after just
+ loading the first page rather than the full 4K).
+
CONFIG_SPL_NAND_BASE
Include nand_base.c in the SPL. Requires
CONFIG_SPL_NAND_DRIVERS.
CONFIG_SPL_LIBGENERIC_SUPPORT
Support for lib/libgeneric.o in SPL binary
+ CONFIG_SPL_PAD_TO
+ Linker address to which the SPL should be padded before
+ appending the SPL payload.
+
CONFIG_SPL_TARGET
Final target image containing SPL and payload. Some SPLs
use an arch-specific makefile fragment instead, for
