I think this would be the best to start - due to the fact that I need 
bitbanging for FPGA flashing, too.

@Prafulla:
in kirkwood/cpu.c
there are 2 functions:
kw_config_gpio()
kw_config_mpp()

If I implement additional functions like
kw_gpio_direction(int gpio, enum direction)
kw_gpio_set(int gpio, int value)
int value kw_gpio_get(int gpio)

If the functions are implemented in cpu.c are they accessible from cmd_xxx.c 
functions?

Would this be ok to get it mainline or should there be an special driver for 
gpio access?

Sorry for my newbie questions :)
