Guys:
I'm porting 2.4.20 to a custom MPC8245 system, based loosely on code
from MV's 2.4.19, in particular the mpc10x.c.
When my kernel boots, I see these:
PCI: Cannot allocate resource region 0 of device 00:02.0
PCI: Cannot allocate resource region 1 of device 00:02.0
PCI: Cannot allocate resource region 2 of device 00:02.0
...
PCI: Cannot allocate resource region 0 of device 00:1f.0
PCI: Cannot allocate resource region 1 of device 00:1f.0
PCI: Cannot allocate resource region 2 of device 00:1f.0
I have two PCI slots, plus an onboard eepro100.
After the kernel boots, my /proc/pci has this:
PCI devices found:
Bus 0, device 0, function 0:

I'm no PCI expert, by far, and I'm not a well-versed PPC hacker
either. (Oh, and simply cutting in mpc10x.c from mv's stuff was
probably a bad idea, too, but I had my reasons). Can someone tell me
what's going on, and how to fix it?
Thanks!
b.g.
