Re: PReP and generic PCI resource assignment

You should initialize the parent pointers in the PCI bus structure with
pointers to resources containing the correct region.

I once hardcoded the parents for the LongTrail, but that code is gone. Now it
tries to set up the parents from information in the OF device, which works
more or less. There are (or were, read as in `were the last time I tried

it, a

few months ago) still some problems, though. One of them is that the

hardcoded

ISA motherboard resources (i8259 and legacy stuff) are requested before PCI
resources are done, and that the PCI bus parent resources were not requested
and thus don't appear in the full resource tree.

Parent pointer should be set properly nowadays on bk _2_4_devel at least.

However, the generic PCI code still wants to add that PCIBIOS_MIN_MEM
value when assigning resources, I bet we should probably #define that
to 0 on PPC.
