This is a relatively large patch. I would love to split it but
currently I am unable to find a nice/clean way. Any suggestions would
be really appreciated:
This currently does 3 broad things:
- Move the PCI device/driver registration to PCI Bus
-- So, introduce PCI bus
-- change EAL to point to this new bus
- remove/refactor existing EAL/*/*pci* code to accommodate this shift
- Test PCI framework.
I could have split test_pci changes into a new patch, but that breaks
compilation after this patchset if test_pci compilation is enabled
(disabled by default). Is that acceptable? (if not, I am stuck with
keeping this set of changes into a single patch).
And, I would appreciate some help in confirming if the changes to
test_pci are OK or not from PCI testing perspective.
