Thanks everyone for the feedback provided. Looks like the bootloader/kernel cross over is now working OK.

My advice to anyone else doing this move - upgrade to the latest version of u-boot before doing the kernel move.

> I am busy with a platform move from the arch/ppc to arch/powerpc tree of the linux kernel. Being relatively new to device trees, I'm trying to ensure I have all the steps covered. The platform is very similar to the AMCC Sequioa (440EPx) and that board has been used as reference for the code changes required. Kernel version is 2.6.25, using u-boot 1.2.0 (CONFIG_OF_xxx enabled, debug output on).
