Hello,
I am trying to run linux on a custom PPC440GP board; however, something goes wrong early in the boot process. I am not sure if the problem is in the device tree or in the memory map.
I've attached the log and the config files.
Thank you,
Jacob

That looks bad. Your device-tree probably. Check the DCR bindings.
I'm on vacation right now, I don't have time to review it in details,
but ask me again next week if you don't find some help in the meantime.
Cheers,
Ben.

Why does this look bad? On 440EPx this looks like this:
UIC0 (32 IRQ sources) at DCR 0xc0
UIC1 (32 IRQ sources) at DCR 0xd0
UIC2 (32 IRQ sources) at DCR 0xe0
So I don't see a problem with the output above.
Cheers,
Stefan

Because of the shit in my eyes :-) I misread 0x00 for some reason...
