--- changes for v2: - rebase to TOT - adapted to new spl framework - add USB support - MDIO Clk only 1MHz - LED: set LED in spl code, and clear them after 1 second - add "bdinfo" command - add nandrbl board specific command for switching between rbl and uboot ecc calculation algorithm

changes for v3: - add CONFIG_SYS_NAND_HW_ECC_OOBFIRST

changes for v4: - add comments from Igor Grinberg - remove in board/ait/cam_enc_4xx/Makefile unnecessary targets clean, distcelan - use CONFIG_MACH_TYPE option - removed some unnecessary brackets - new patch: add a weak enable_vbus() in drivers/usb/musb/davinci.c - add a comment to an "#else" to make it clearer to which "#if" it belongs

- fix ALL to ALL-y in board config.mk, and add this only if CONFIG_SPL_BUILD is not set.

changes for v6: - add CONFIG_SPL_NAND_LOAD define
