OvmfPkg: PlatformBdsLib: Platform dependent PCI/IRQ initialization
Merge PciInitialization() and AcpiInitialization() into a single
function, PciAcpiInitialization(), and use a PCD set during PEI to
detect the underlying platform type (PIIX4 or Q35/MCH) and therefore
the addresses of the registers to be initialized.
Add LNK[A-H] routing target initialization for the Q35 platform.
Additionally, initialize PCI_INTERRUPT_LINE registers for the typical
set of PCI devices included by QEMU with the Q35 machine type. The
corresponding PIIX4 initialization of PCI_INTERRUPT_LINE registers is
cleaned up and the list of PIIX4 PCI devices updated to the list
typically included with QEMU.
NOTE: The list of PCI devices for which we initialize PCI_INTERRUPT_LINE
is hard-coded, and, depending on how QEMU devices are configured on
the command line, may miss some devices, or (harmlessly) attempt to
initialize devices which are not present in the system. A subsequent
patch will replace this hard-coded list with a mechanism to correctly
initialize PCI_INTERRUPT_LINE for applicable present PCI devices only.
