Hi,

via anonymous rsync from montavista server. i followed the instructions at
http://penguinppc.org/dev/kernel.shtml

Unfortunately, neither of these docs talks about tailoring the kernel to
custom hardware. They only state that "some changes" have to be applied to
the startup code. I need some more specific information, because I'm not a
expert PPC guru.

this means that i also have to port u-boot and use 2 bootloaders in
sequence, or port u-boot's decompressor code to our own bootloader. Sigh.

Arm Linux provides a self-decompressing zImage. I thought it could be
possible to configure the ppc kernel just like that.

Thanx anyway,
Patrick
