[U-Boot-Users] [PATCH] PPC-44x: Add Open Firmware support to AMCC Yosemite

[Ira Snyder <iws@ovro.caltech.edu>]

Hello U-Boot users,

This is my first patch, so any suggestions would be welcome.

I have an AMCC Yosemite board, which I recently updated to use the
recent ARCH=powerpc work from mainline Linux. Without this patch, trying
to boot from a uImage does not work. The kernel panics while trying to
parse the device tree blob. Note that a cuImage works fine previous to
this patch.

Also, I noticed that when I started booting with a uImage and dtb, that
eth0 had a MAC address of 00:00:00:00:00:00. Adding
#define CONFIG_HAS_ETH0 1 fixed this issue, by setting the MAC address
via the eth0addr variable in U-Boot.

I tested the following setups:
1) Old ARCH=ppc 2.6.13 kernel
2) New ARCH=powerpc 2.6.26rc0 kernel (cuImage)
3) New ARCH=powerpc 2.6.26rc0 kernel (uImage + dtb)

I ran MAKEALL both with and without the patch. The only changes in output
were a ~20kB increase in image size for the yellowstone and yosemite boards.

Thanks for all of the great work.
Ira
