ath79: fix source of label MAC address for Ubiquiti XM devices
In d421a8b94489 ("ath79: read label MAC address from flash instead of using phy0/phy1") the source of the label MAC address was changed for devices just reading it from phy0. To get rid of the dependency from phy startup, addresses were read directly from the flash locations that are used to initialize the phy MAC addresses. Unfortunately, it turned out that Ubiquiti XM devices seem to have different flash locations than expected, and also seem to have specific locations for different devices (all in art/EEPROM): 0xe012 AR9280 Nanostation M2 - 0x120c 0xe035 AR9280 Nanostation M3 - 0x120c 0xe1b2 AR9280 Rocket M2 - 0x120c 0xe1c3 AR9280 Rocket M3 - 0x120c 0xe1b5 AR9280 Rocket M5 - 0x120c 0xe2d5 AR9280 Bullet M2 Titanium - 0x120c 0xe2b5 AR9280 Nanobridge M5 - 0x120c 0xe202 AR9280 Bullet M2 - 0x120c 0xe232 AR9287 Nanobridge M2 - 0x110c 0xe4a2 AR9285 AirRouter - 0xa0bf Picostation M2 - 0x120c and 0xa0bf Nanostation Loco M2 - not in 0x120c, other locations not checked An additional problem of the Ubiquiti device support in OpenWrt is that we provide images that match several subvariants of the devices, which might have different MAC address locations. Given that reading the address from phy0 in 02_network _is_ working for the ath79 target in general, it does not seem reasonable to rebuild a complex MAC address retrieval mechanism which is already present in the ath9k driver. So, this patch reverts the label MAC address source for Ubiquiti XM devices (and the Unifi AP) to /sys/class/ieee80211/phy0/macaddress. This doesn't affect XW and Unifi AC devices, where the label MAC address source is defined via device tree. For alfa-network,ap121f the location 0x1002 is kept, as this has been verified during device support preparation in PR #2199.
