LinuxPPC: porting to new platforms

I've been trying to get linuxppc running on a Motorola ADS board for
some time now. It seems that the ADS/FADS boards are quite horrible
from the mail I've read on this list. I have now decided to take the
plunge and port it to a custom MPC860 board.
Are there any documents that will help in the port ? I need information
on which files need changing etc and what strategies to adopt.
At the moment, I am playing around with the 2.2.11 kernel sources which
I got from a kernel mirror. I notice that the support for BSE and RPX
boards is not in this source. Are there some PPC specific kernel
archives I should be getting instead ?
I don't think 2.2.11 is the latest in the 2.2 series anymore. I want to
make my port official and included in the kernel sources. What is the
best way to go about this ? Is it recommended to use the latest
experimental kernels (2.3.x) or the latest 2.2 kerenl ? Is 2.2.11 ok to
develop with or should I get the latest 2.2 kernel ?
Anyway, I am basing my port on the MBX stuff as it is the only 860 port
in the 2.2.11 archive I have. I think the BSE or FADS port would be
closer to my custom board though. I basically have copied the mbxboot/
directory to myboot/ and have altered config.in. I tried compiling and
found that it was trying to do the chrp build. I think I need to add
support for my_defconfig files. The mbx_defconconfig files says that it
is generated automatically by make menuconfig and not to edit it. How
do I get make menuconfig to generate my_defconfig etc. Is there
anything else I have to do.
