DT version of kirkwood_ge0x_init()

[Gerlando Falauto]

Hi everyone,

I noticed how most of the DT-aware board-setup files only have a single
<board>_init() function, calling kirkwood_ge00_init() with a struct 
mv643xx_eth_platform_data as a single argument.

I was wondering -- is there a reason why we cannot remove all this 
board-specific code and move all this to the DT?

I noticed how NS2 can somehow trick this value depeding on the 
compatible string, so I assume it's not really *THAT* early, as the 
whole DT infrastructure is already available:

	if (of_machine_is_compatible("lacie,cloudbox") ||
	    of_machine_is_compatible("lacie,netspace_lite_v2") ||
	    of_machine_is_compatible("lacie,netspace_mini_v2"))
		ns2_ge00_data.phy_addr = MV643XX_ETH_PHY_ADDR(0);
	kirkwood_ge00_init(&ns2_ge00_data);

I guess we could remove a lot of board-specific code if we could move 
this last bit of information to the DT.
Unless compatibility with existing DTs is an issue -- but what about new 
boards?

I would really love to have all our boards under a single 
CONFIG_<FAMILY>_DT and a single compatible string, with all the 
differences within the DTs itself -- no more #ifdef CONFIG_<BOARD>, no 
more of_machine_is_compatible("boardXXX").

Any feedback (swearwords included -- in case I'm talking non-sense) 
would be more than welcome.

Thank you!
