Hello,
Your patch is word-wrapped. It also lacks the Signed-off-by tag, which
is required.
I apologize please see an updated patch below.
The changelog sounds as if there are bugs being fixed here, but really
you're adding support for something entirely new. The yosemite board
comes with U-Boot, which uses uImages. You seem to be adding support
for using simpleboot on the Yosemite board. Is that correct?
Yes, the patch ensures the simpleboot image works on the Yosemite board. I was
under the impression the code was broken as one can build a simpleImage for the
Yosemite board as described in Documentation/powerpc/bootwrapper.txt without any
modification on a vanilla kernel, although the resulting image does not work
without the following patches.
> You can't do this. If you hard code the MAC address of whatever board

> mechansim.
Oops, sorry I forgot to pull out the debug code...
