hi
I am a student, I represent a group of friends running a couple of
opensource projects(1), and we are lost with this(2) problem.

I wrote here(2) a couple of years ago, we are still working with kernel
4.11.0 and there is broken support for initializing the PCI.

The PCI initialization of the PPC405GP seems wrong and every
kernel >= 2.6.26 is not able to correctly address the PDC20265

an interesting note is:
kernel 2.6.26 can be compiled with arch=ppc and arch=powerpc

when compiled with arch=ppc the promise PDC20265 chip is correctly
managed; while when compiled with arch=powerpc the PDC20265 is not
correctly managed

any idea? advice? help? suggestion?
a good place to discuss it?

thanks
Carlo
