[U-Boot] [PATCH V9 7/9] devkit8000: Add nand-spl support for new SPL

[Simon Schwarz]

Add NAND SPL support to the devkit8000 config

Signed-off-by: Simon Schwarz <simonschwarzcor at gmail.com>
---
V1 changes:
ADD devkit8000_nand to board.cfg
ADD nand_spl Makefile, llinker script, spl-devkit8000.c
ADD config ecc, SRAM, SPL to board config
ADD CONFIG_SYS_SRAM_START and _SIZE to board config
ADD CONFIG_SYS_SPL_TEXT_BASE, _MAX_SIZE and SPL_STACK to board config

V2 changes:
ADD CONFIG_SPL and LIBCOMMON, LIBDISK, I2C, LIBGENERIC, SERIAL, POWER, NAND and
	CONFIG_SPL_LDSCRIPT to board config
CHG renamed CONFIG_SYS_SPL_* to CONFIG_SPL_*
ADD CONFIG_SYS_NAND_U_BOOT_START, _OFFS, _SIZE, _DST to board config: Where to
     expect u-boot and where to load it.
ADD some barrier to not build board_eth_init in SPL
DEL no changes to board.cfg
DEL everything used the old nand_spl layout (Makefile, linker script,
        spl-devkit8000.c)
CHG cosmetic

V3 changes:
CHG Deleted wrong comment

V4 changes:
CHG CONFIG_SYS_SRAM_SIZE NOW has the right value
CHG cosmetic - corrected style problems

V5 changes:
nothing

V6 changes:
nothing

V7 changes:
ADD MMC dummy defines to prevent #ifedf clutter in spl.c
DEL CONFIG_SYS_NAND_U_BOOT_DST

V8 changes:
ADD CONFIG_SPL_NAND_SIMPLE

V9 changes:
DEL unused and untested MMC bootconfig

Transition from V1 to V2 also includes that this patch is now based on
- the new SPL layout by Aneesh V and Daniel Schwierzeck
- the OMAP4 SPL patches by Aneesh V

This is the successor of "[U-Boot,5/5] devkit8000 nand_spl: add nand_spl
support"
