+- SPL framework
+ CONFIG_SPL
+ Enable building of SPL globally.
+
+ CONFIG_SPL_LDSCRIPT
+ LDSCRIPT for linking the SPL binary.
+
+ CONFIG_SPL_MAX_SIZE
+ Maximum binary size (text, data and rodata) of the SPL binary.
+
+ CONFIG_SPL_TEXT_BASE
+ TEXT_BASE for linking the SPL binary.
+
+ CONFIG_SPL_RELOC_TEXT_BASE
+ Address to relocate to. If unspecified, this is equal to
+ CONFIG_SPL_TEXT_BASE (i.e. no relocation is done).
+
+ CONFIG_SPL_BSS_START_ADDR
+ Link address for the BSS within the SPL binary.
+
+ CONFIG_SPL_BSS_MAX_SIZE
+ Maximum binary size of the BSS section of the SPL binary.
+
+ CONFIG_SPL_STACK
+ Adress of the start of the stack SPL will use
+
+ CONFIG_SPL_RELOC_STACK
+ Adress of the start of the stack SPL will use after
+ relocation. If unspecified, this is equal to
+ CONFIG_SPL_STACK.
+
+ CONFIG_SYS_SPL_MALLOC_START
+ Starting address of the malloc pool used in SPL.
+
+ CONFIG_SYS_SPL_MALLOC_SIZE
+ The size of the malloc pool used in SPL.
+
+ CONFIG_SPL_FRAMEWORK
+ Enable the SPL framework under common/. This framework
+ supports MMC, NAND and YMODEM loading of U-Boot and NAND
+ NAND loading of the Linux Kernel.
+
+ CONFIG_SPL_DISPLAY_PRINT
+ For ARM, enable an optional function to print more information
+ about the running system.
+
+ CONFIG_SPL_INIT_MINIMAL
+ Arch init code should be built for a very small image
+
+ CONFIG_SPL_LIBCOMMON_SUPPORT
+ Support for common/libcommon.o in SPL binary
+
+ CONFIG_SPL_LIBDISK_SUPPORT
+ Support for disk/libdisk.o in SPL binary
+
+ CONFIG_SPL_I2C_SUPPORT
+ Support for drivers/i2c/libi2c.o in SPL binary
+
+ CONFIG_SPL_GPIO_SUPPORT
+ Support for drivers/gpio/libgpio.o in SPL binary
+
+ CONFIG_SPL_MMC_SUPPORT
+ Support for drivers/mmc/libmmc.o in SPL binary
+
+ CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR,
+ CONFIG_SYS_U_BOOT_MAX_SIZE_SECTORS,
+ CONFIG_SYS_MMC_SD_FAT_BOOT_PARTITION
+ Address, size and partition on the MMC to load U-Boot from
+ when the MMC is being used in raw mode.
+
+ CONFIG_SPL_FAT_SUPPORT
+ Support for fs/fat/libfat.o in SPL binary
+
+ 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_NAND_DRIVERS
+ SPL uses normal NAND drivers, not minimal drivers.
+
+ CONFIG_SPL_NAND_ECC
+ Include standard software ECC in the SPL
+
+ CONFIG_SPL_NAND_SIMPLE
+ Support for NAND boot using simple NAND drivers that
+ expose the cmd_ctrl() interface.
+
+ CONFIG_SYS_NAND_5_ADDR_CYCLE, CONFIG_SYS_NAND_PAGE_COUNT,
+ CONFIG_SYS_NAND_PAGE_SIZE, CONFIG_SYS_NAND_OOBSIZE,
+ CONFIG_SYS_NAND_BLOCK_SIZE, CONFIG_SYS_NAND_BAD_BLOCK_POS,
+ CONFIG_SYS_NAND_ECCPOS, CONFIG_SYS_NAND_ECCSIZE,
+ CONFIG_SYS_NAND_ECCBYTES
+ Defines the size and behavior of the NAND that SPL uses
+ to read U-Boot
+
+ CONFIG_SYS_NAND_U_BOOT_OFFS
+ Location in NAND to read U-Boot from
+
+ CONFIG_SYS_NAND_U_BOOT_DST
+ Location in memory to load U-Boot to
+
+ CONFIG_SYS_NAND_U_BOOT_SIZE
+ Size of image to load
+
+ CONFIG_SYS_NAND_U_BOOT_START
+ Entry point in loaded image to jump to
+
+ CONFIG_SYS_NAND_HW_ECC_OOBFIRST
+ Define this if you need to first read the OOB and then the
+ data. This is used for example on davinci plattforms.
+
+ CONFIG_SPL_OMAP3_ID_NAND
+ Support for an OMAP3-specific set of functions to return the
+ ID and MFR of the first attached NAND chip, if present.
+
+ CONFIG_SPL_SERIAL_SUPPORT
+ Support for drivers/serial/libserial.o in SPL binary
+
+ CONFIG_SPL_SPI_FLASH_SUPPORT
+ Support for drivers/mtd/spi/libspi_flash.o in SPL binary
+
+ CONFIG_SPL_SPI_SUPPORT
+ Support for drivers/spi/libspi.o in SPL binary
+
+ CONFIG_SPL_RAM_DEVICE
+ Support for running image already present in ram, in SPL binary
+
+ 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
+ example if more than one image needs to be produced.
