[PATCH] Support for AMCC Yosemite 440EP Eval Board
This patch adds support for the new AMCC Yosemite 440EP Eval Board. I tested it on the both Bamboo and Yosemite boards using the 2.6.12 kernel.

How about a patch against a more recent kernel?
This patch has three dependencies:
2005-04-07 Wade Farnsworth's PPC440EP SoC and Bamboo board support
Please use the patches Wade sent yesterday to this list.

OK, here we go...

Hmmm. You seem to include not only the Yosemite but also the Yellowstone with
a different processor type (440GR) into the bamboo platform file. I would
prefer seperate platform files for the different boards, especially since the
differences are not marginal.

Well, why don't you make separate board port instead if hacking Bamboo one? IMHO, direction you are going is creating a lot of mess. If there is some common parts between Bamboo and Yosemite, the right way is to factor out this stuff from Bamboo port. Also, your patch is mangled - some lines are wrapped. -- Eugene
