[PATCH 1/3] AT91: update at91_eth_data for ETX2-3 on PA10-11

[Tim Barr]

I see a bigger problem here. It is more of an issue of how to properly
handle signals that have more than one pin assignment option. Is there
any sort of kernel design spec for this? As it stands now, I have to
modify the at91sam9260devices.c file every time I change kernels,
because some of the MII pins assigned are not the ones I use in my
design. I think that any pin that has more than one assignment option
should be set in the structures passed by the board file.
