2025-09-19kernel: pci: Add PCI lookup routineIan Moffett
This commit adds a new 'lookup_type_t' for representing the various kinds of lookups one can perform on the PCI bus. The actual code to drive the lookups is exposed as the pci_bus_lookup() routine. When doing a lookup of a PCI device, you must specify the kind of lookup to perform. If a PCI_LU_CLASSREV is requested, only the PCI class and subclass fields in the PCI lookup are used. If the PCI_LU_VENDEV is requested, only the PCI vendor ID and device ID are used in the lookup. Signed-off-by: Ian Moffett <ian@osmora.org>
