Your patch is line wrapped. Please fix this and resubmit.
One quick comment without looking too deep into your patch:
You are introducing a board specific flash driver. This should not be
necessary anymore, since the common CFI driver now also has an interface to
support non CFI compatible flash chips. What flash chips are you using?
Please see actux4 for example (CFG_FLASH_LEGACY_256Kx8).
Best regards,
Stefan

I will check your point with the flash driver...
Hope this time the patch is not line wrapped.

It is again. I suggest that you first send this message to yourself, until you
figured out how to do it correctly. And if you are working with git, I
strongly encourage you to use git-send-email to send patches.

Would you mind changing this name to board_eth_initialize(bd_t *bi)?
I'm working on a rework of the net library and making this name change
now will avoid doing it later. I think you'll be able to figure out
where this is going...

It's STILL line-wrapped.
Can you please test this OFF LIST until you are SURE it's working?
Thanks.

God grant me the senility to accept the things I cannot change, The
frustration to try to change things I cannot affect, and the wisdom

Hm. I have a patch to clean up tsec initialization a bit. I'm
wondering how this affects the tsec (and my patch). And there are
other issues with calling the function something generic like that.
The Freescale SOCs have 2 or more (I think we have 5 on one of our
chips) TSEC devices. How do you deal with separating out multiple
controllers?
Also, won't this break if you have more than one type of controller on a board?

Put multiple calls to the chip-specific init function in
board_eth_initialize()
> Also, won't this break if you have more than one type of controller on a board?
No, just make any sort of chip-specific init calls you need from
board_eth_initialize().
The idea behind board_eth_initialize() is, if I get this correctly:
* All board-specific knowledge (number and type of controllers, etc.)
is contained within it.
* It has the same name and signature on all boards, so we don't need
a gazillion #ifdefs in net/eth.c
* New boards don't need to patch anything under net/, so the
probability of conflicts is reduced.
