They all share an identical register layout with only a few minor differences (except the PB1000) in bit functions and base addresses. This patch - adds a primitive facility to initialize and use these external registers, - replaces all occurrences of bcsr->xxx accesses with calls to the new functions (the pb1200 cascade irq handling code is special). - collects BCSR register information scattered throughout the board headers in a central place.

We now pass PHY-speficic configurations through platform_data but for compatibility the driver still assumes the default settings (search for PHY1 on MAC0) when no platform_data is passed. Tested on my MTX-1 board. Signed-off-by: Florian Fainelli Cc: linux-mips@linux-mips.org Cc: netdev@vger.kernel.org Acked-by: David S.
