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
