Kirkwood family controllers are highly integrated SOCs based on Feroceon-88FR131/Sheeva-88SV131 cpu core.
SOC versions supported:- 1) 88F6281-A0 define CONFIG_KW88F6281_A0 2) 88F6192-A0 define CONFIG_KW88F6192_A0
Other supported features:- 1) get_random_hex() fucntion 2) SPI port controller driver 3) PCI Express port initialization

Reviewed-by: Ronen Shitrit rshitrit@marvell.com Signed-off-by: Prafulla Wadaskar prafulla@marvell.com --- Change log: v2: crated arch-kirkwood and moved some header files there renamed and moved spi.c to drivers/spi/ renamed and moved serial.c to drivers/serial/ doimage utility removed soc_init.S renamed as lowlevel_init.S debug prints removed
v3: lowlevel_init.S converted to lowlevel_init.c removed BITxx macros, removed entire assembly code Added CONFIG_ARCH_LOWLEVE_INIT support for arm926ejs core updated as per review commens for v2
v4: updated as per review comments for v3 print_cpuinfo used to display Soc info arch_misc_init support created and used for lib_arm mandatory readl/write macros used asm/cache.h asm/arch/spi.h asm//arch/serial.h created and used
v5: updated as per review comments for v4 cosmetic updates, arch_misc_init and arch_cpu_init used start.S updated to call arch_lowlevel_init in case if lowlevl_init is skipped bug fix in cpu.c
v6: lowlevel_init.S removed code moved under arch_cpu_init
v7: include <asm/arch/kirkwood.h> added to each c file reference removed from include/asm/config.h arch_misc_init defination kept as it is in include/common.h bugfixed in get_random_hex function
v7.1: u-boot.lds moved from board specific to kirkwood
v8: mpp configuration added u-boot.lsd and config.mk removed serial driver removed and used ns16550 register offsets replaced by c struct updated as per review comments for v7
v9: updated as per v8 review comments removed all (u32) typecasts spi driver bugfix and magic constants removed tabs used for all indentation
