Ruiyu Ni 05070c1b47 MdeModulePkg/PciBus: do not improperly degrade resource
PciBus driver originally always degrade (64->32) the MMIO resource
for PCI BAR when the PCI device contains option ROM.
But the degrade causes the PCI device can only use resource below 4GB
which makes the resource allocation fails when the PCI device wants
very big MMIO.
The patch follows the PI spec (ECR 1529) to honor the granularity
setting for PCI BAR from IncompatiblePciDeviceSupport so that even
for PCI device which contains option ROM, the degrade doesn't happen
if IncompatiblePciDeviceSupport returns 64 as granularity.

PciHotPlugSupport.c The PCI HotPlug Init Protocol returns a list of Root HPC, but it is possible that some HPCs in the list are not found during PCI enumeration. In this case, the PCI HotPlug Init Protocol.InitializeRootHpc() will not be called for the un-found HPCs. However, in AllRootHPCInitialized(), all reported HPCs are checked to see if it has been initialized, so TIME_OUT happens. 2010-11-22 07:16:02 +00:00
