General question on upgrading Linux version

Hi All,
We are using MPC8541 processor from freescale. Our current kernel
version is based on 2.6.11 plus some patches provided by Freescale. I
would like to update our Kernel version to a more recent version. 
I would greatly appreciate if you could provide me with some general
guideline on how to proceed .....
 
Many thanks in advance,
B

You should be able to check out the latest sources from git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc.git

You will probably also need a newer u-boot from here:

git://www.denx.de/git/u-boot-mpc85xx.git

Please tell me if you have any problems using these.

The current stable kernel release is 2.6.21. Could I use that tree
instead ?

Currently we are using uboot 1.2. Do I have to update the u-boot version
also or I can bypass that for now?
Thanks,

I am not sure about the exact versions but you propably need to switch
over from devfs to udev. (usually no big deal)

I follow the latest stable and latest-git from kernel.org. I didn't run
into major problems over here for MPC8540, however I am still on the old
ARCH=ppc. ARCH=powerpc compiles fine as well. I just had no time to have
a closer look at the DeviceTree/OpenFirmware/U-Boot stuff.

Is there any brief HowTo migrate from ppc to powerpc including u-boot?

Best greets,
