I'm glad someone else is looking at the air-gateway as well. Here was
my approach:
I added the following to the bottom of mach-ubnt-xm.c
#define AIRGW_MAC0_OFFSET 0x0000
#define AIRGW_MAC1_OFFSET 0x0006
#define AIRGW_CALDATA_OFFSET 0x1000
static struct gpio_led ubnt_airgateway_gpio_leds[] __initdata = {
{
.name = "ubnt:blue",
.gpio = 0,
}, {
.name = "ubnt:white",
.gpio = 1,
},
};
static void __init ubnt_airgateway_setup(void)
{
u32 t;
u8 *art = (u8 *) KSEG1ADDR(0x1fff0000);
ath79_gpio_function_disable(AR933X_GPIO_FUNC_ETH_SWITCH_LED0_EN |
AR933X_GPIO_FUNC_ETH_SWITCH_LED1_EN |
AR933X_GPIO_FUNC_ETH_SWITCH_LED2_EN |
AR933X_GPIO_FUNC_ETH_SWITCH_LED3_EN |
AR933X_GPIO_FUNC_ETH_SWITCH_LED4_EN);
t = ath79_reset_rr(AR933X_RESET_REG_BOOTSTRAP);
t |= AR933X_BOOTSTRAP_MDIO_GPIO_EN;
ath79_reset_wr(AR933X_RESET_REG_BOOTSTRAP, t);
ath79_register_m25p80(NULL);
ath79_register_leds_gpio(-1, ARRAY_SIZE(ubnt_airgateway_gpio_leds),
ubnt_airgateway_gpio_leds);
ath79_init_mac(ath79_eth1_data.mac_addr,
art + AIRGW_MAC0_OFFSET, 0);
ath79_init_mac(ath79_eth0_data.mac_addr,
art + AIRGW_MAC1_OFFSET, 0);
ath79_register_mdio(0, 0x0);
ath79_register_eth(1);
ath79_register_eth(0);
ath79_register_wmac(art + AIRGW_CALDATA_OFFSET, NULL);
ath79_register_usb();
}
MIPS_MACHINE(ATH79_MACH_UBNT_AIRGW, "UBNT-AGW", "Ubiquiti AirGateway",
ubnt_airgateway_setup);
Add an entry to machtypes.h
ATH79_MACH_UBNT_AIRGW, /* Ubiquiti AirGateway */
Add the target/linux/ar71xx/image/Makefile:
$(eval $(call
SingleProfile,UBNTXM,$(fs_64k),UBNTAIRGW,ubnt-air-gateway,UBNT-AGW,ttyATH0,115200,XM,UBNTAirGW,ar933x))
This also builds a separate image, for the air-gateway..
My only problem is that the watchdog isn't working correctly. I get
random reboots on it, i tried applying Felix's ar933x watchdog timer
fix ( i thought that may have been causing it, but didn't seem to help
). Anyway, that's my start, I was able to atleast get it running. The
architecture needs to get cleaned up a bit, hence why I haven't built
any patches and attempted to submit them ( haven't had enough time :-/
)
