[U-Boot] [PATCH v10] Marvell Kirkwood family SOC support

Prafulla Wadaskar
2009-05-21T20:24:29Z

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

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

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

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
