[SeaBIOS] [PATCH 0/2] pciinit: fix overflow when bar allocation

[Isaku Yamahata]

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.
