While the AR9331 has a gigabit MAC towards the internal switch, the
integrated PHYs however are only 100-base-tx capable. The existing code
however advertieses gigabit capability in the link status word. If you
attach such a PHY to a gigabit capable switch on the remote end, with
some probability it attempts to negotiate gigabit and fails, falling
baco to the AR9331 assuming a 10mbit half-duplex link. This has been
observed quite frequently with the Carambola2 and gigabit capable
switches.
In ath79_register_eth(), "pdata->has_gbit = 1;" is set unconditionally
for both AR9331 ethernet ports. This is most likely wrong. Despite the
two MAC IP cores being gigabit MACs, the MAC for eth1 is connected to a
100base-T PHY via MII. The has_gbit attribute is used in the ethernet
driver to determine the supported link modes.
So either pdata->has_gbit is not set to 1 anymore, or the ethernet
driver needs to be modified to determine the advertised link code word
on another criteria than pdata->has_gbit. This patch implements the
former solution.

This sets the MAC address of the WLAN interface to the "official" primary MAC
address (the one on the label under the devices, and the one used with the stock
firmware). The MAC address used so far (primary-1) isn't even used at all with
the stock firmware, which sets (primary) on LAN and WLAN and (primary+1) on the
WAN interface (like OpenWrt does with this patch).

The RB2011UiAS is almost exactly the same as the RB2011UAS, which is
already supported. Hardware-wise, it adds a passive power injector on
Eth10. Software-wise, Routerboot passes a different board name on the
kernel command line. Hence the need for a patch.
Not yet working:
* touchscreen: doesn't work on RB2011UAS either. The touchscreen itself
seems to be driven by an ADS7843-compatible IC, but figuring out which
GPIO pins it's connected to is work for the future.
* control of power injector: remains off. Probably also GPIO-controlled.

sizeof(array_from_function_definition) gives back the size of the pointer.
sizeof(type) * array_size should be used in memset.

The ar71xx platform always uses the eth0 interface to provide
access to the device in failsafe mode. Due to this, failsafe
access is broken on devices where the LAN ports are connected
to the 'eth1' interface.
Update the relevant script to correctly set the ifname variable
for these devices.

The RB91x boards are using a serial shift register
connected to the SPI bus to drive some of the LEDs.
Rework the board setup code to register a SPI device
for that. This makes it possible to use the 'spi-74x164'
driver to control the device.

That will be used to drive the 74HC595 serial-in/parallel-out
8-bits shift register which can be found on some RouterBOARDs.
