The PCI_DOMAIN has two mem resource, root calculate the mem base correctly.
But PCI_DOMAIN get the wrong base.

root mem limit=0x00febfffff, size=0x0022700000, align=28, base=0x00d0000000
Allocating VGA resource PCI: 03:00.0
PCI_DOMAIN: 0000 00 <- [0x0000001000 - 0x0000005fff] io
PCI_DOMAIN: 0000 01 <- [0x00f8000000 - 0x01007fffff] prefmem
PCI_DOMAIN: 0000 02 <- [0x00f8000000 - 0x00fe6fffff] mem

Ouch.  If you can boot the board in linux please give me an lspci -vvv

I don't have enough information to even guess what is going on.
I need to know what the size and limit of the resources are,
so I can walk through the code and see what it would do.

At the moment I can't even begin to guess what is going wrong.

The obvious problem of doubly allocating a base register does
not appear to apply.  I am using the standard compute_allocate_resource
function which should traverse the bus and do the right thing.

Unless my rewrite of the limit calculation code is causing a problem.

I just don't know where to look.
