YhLu,
Which mainboard are you working on ? Is it some board that's already in the public tree ? If it is already in the public tree, could be commit you change so people on the list can try it.
Don't worry about broken code, every mainboard is broken in the current CVS.

Align is not assigned and it will be used to calculate the base too. (using resource_max)

Eric,
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.
