This patch adds support for the Keymile suen3 board which is based on the Marvell Kirkwood (88F6281) SoC. As this is a variant of the mgcoge2_arm_p1a board, this board also uses common code stored in board/keymile/km_arm/km_arm.c

Signed-off-by: Heiko Schocher hs@denx.de --- - changes since v1: added comments from Wolfgang Denk: get rid of flash_info_t define in board config (to get this working patch 1/2 is introduced/needed)

- changes since v2: added comments from Wolfgang Denk - rearranged if/else in do_spi_toggle() - added I/O accessor functions for bootcounter

- changes since v3: added comment Scott Wood - removed nand_init in do_spi_toggle()

added comments from Prafulla Wadagaskar - km-arm.h renamed to km_arm.h - reworked eeprom_write_enable() (deleted it) (when reviewing this function, it cropped up, that this pin is connected through a gpio pin, not as in previous version, through the boco (a FPGA)) - moved set_sda(), set_scl(), get_sda(), get_scl() to km_arm.c - split patch in 4 patches (for each board an extra patch) - renamed sdramregs.txt in kwbimage.cfg, also license info added.
