[Qemu-devel] [PATCH] pci: remove explicit check to 64K ioport size

2013-09-13 Thread Hervé Poussineau
This check is useless, as bigger addresses will be ignored when added to 'io' MemoryRegion, which has a size of 64K. However, some architectures don't use the 'io' MemoryRegion, like the alpha and versatile platforms. They create a PCI I/O region bigger than 64K, so let them handle PCI I/O BARs in
