For a hot plug bridge with device attached, PciBusDxe driver reserves the resources which equal to the total amount of padding resource returned from HotPlug->GetResourcePadding() and the actual occupied resource by the attached device. The behavior is incorrect. Correct behavior is to reserve the bigger one between the padding resource and the actual occupied resource.
The first patch is to revert the previous two commits which combine the debug log fix and resource reservation fix together.
