PCI: Add "pci=hpmmiosize" and "pci=hpmmioprefsize" parameters
The existing "pci=hpmemsize=nn[KMG]" kernel parameter overrides the default
size of both the non-prefetchable and the prefetchable MMIO windows for
hotplug bridges.
Add "pci=hpmmiosize=nn[KMG]" to override the default size of only the
non-prefetchable MMIO window.
Add "pci=hpmmioprefsize=nn[KMG]" to override the default size of only the
prefetchable MMIO window.
