As long as Linux boots on the board in any form, it should not be
difficult. My first mpc5121e devel board only had serial port and
ethernet functional, and after a few days work, openSUSE booted on it :-)
Basically there are two possibilities:
- if the current SuSE kernel can't be patched to boot on the board, then
one can compile everything in a monster monolithic kernel to support
installation and booting. This approach worked with both openSUSE and
Debian/Ubuntu on the mpc5121e and other boards.
- if the current SuSE kernel can be configured and/or patched to boot on
a given board, then it is more elegant to use SuSE kernel sources with
default config + additional hw support (I used mkinstallinitrd or
something similar, I can't recall any more). This is what I used for the
mpc8610 developer system
Of course, one can skip creating an installer, when there is an
installed PPC system available. Just make a copy to NFS and boot a
kernel from TFTP. Possibilites are endless :-)
Once factory is synced out again and I got a little time, I try to port
it to my mpc8610 (G4 on lots of steroids :-) ) system, as that is my
fastest PPC machine at the moment.
Bye,
CzP
