[U-Boot-Users] [PATCH 1/2] ppc4xx: Add DU440 board support

[Matthias Fuchs <matthias.fuchs@esd-electronics.com>]

Hi Wolfgang,

as you might have noticed the DU440 board is havily based on seuqoia code.
Nearly all of your comments apply to that board as well. I thought of the
sequoia code as exemplary reference code. And I prefer not to reformat comments
when copy and pasting from one board to another.

But if you really insist of these changes I will change the patch.

Good idea. Thanks.

Please not. The DU440 board will get an updated smi_lynxem driver with support for the
SM722 soon. My current hack is to dirty for submission and I just got some more register
dumps from SM to support more videomodes. I will need this commented out code to test it.
I plan to remove it later.

Ack. May I put my name on it? The source of this code has no copyright either.

This is new to me. But I just noticed that all other boards have been updated according to this. So will I.

I will update my patches. Perhaps you can comment on my comments above.
