ie, for gpio access.
where can i find them?
in data sheets? where can i find the data sheets for bcm4702/4710?

like in the mmc.c driver,
static volatile uint32 *gpioaddr_input = (uint32 *)0xb8000060;
static volatile uint32 *gpioaddr_output = (uint32 *)0xb8000064;
static volatile uint32 *gpioaddr_enable = (uint32 *)0xb8000068;
static volatile uint32 *gpioaddr_control = (uint32 *)0xb800006c;

how did they know the address 0xb8000060 and so on?

the matter is that these addresses seems doesn't work on my bcm4702 based buffalo wbr-g54.
i want to check it to c what the problem is.

thanx in advance.
