PciHotPlugInitDxe has a static variable called "mPadding" (of type RESOURCE_PADDING), which describes two constant resource reservations: - MmioPadding: 2MB of non-prefetchable (hence 32-bit) MMIO space, - IoPadding: 512B of IO space. In the GetResourcePadding() member function of EFI_PCI_HOT_PLUG_INIT_PROTOCOL, the driver outputs a dynamically allocated verbatim copy of "mPadding", for PciBusDxe to consume in its ApplyResourcePadding() function. In a later patch, we're going to compose the set of resource reservations dynamically, based on QEMU hints. Generalize the RESOURCE_PADDING structure so that we may generate (or not generate) each resource type individually: - Replace the named "MmioPadding" and "IoPadding" fields in RESOURCE_PADDING with an array of descriptors, - remove "mPadding", - in GetResourcePadding(), request the same (default) reservations as before, as if we attempted and failed to fetch the QEMU hints.
