Patch description: This patch set fixes PCI bar allocation when bar overflow occured. I checked if pmm_alloc facility can be used, but it doesn't suit for pci bar allocation. So I resulted in new API, pci_region which encapsulates region allocation and overflow checks. The first patch introduces pci_region, and the second patch fixes the overflow case with pci_region. Isaku Yamahata (2): pci: introduce pci_region to manage pci io/memory/prefmemory regions. pciinit: use pci_region functions.
