Ok, like I promised, this was the per-board device registration. Do you prefer something like this:

Subject: [PATCH] alchemy: add au1000-eth platform device (v2)
This patch makes the board code register the au1000-eth
platform device. The au1000-eth platform data can be
overriden with the au1xxx_override_eth0_cfg function
like it has to be done for the Bosporus board.
Changes from v1:
- remove per-board platform.c file
- add an override function to pass custom eth0 platform_data PHY settings
