Picks up the Phase A foundation from plan § v4.7 v4.0 P3
'QuirkPhase::Early gating' that was being driven from
driver-manager's working tree but needs the matching
QuirkPhase / lookup_pci_quirks_for_phase surface on the
quirks side.
Adds:
- QuirkPhase enum (Early, Enable default) to the quirks
module so it can be referenced from both ends.
- phase: QuirkPhase field on PciQuirkEntry (defaults to Enable)
so existing PCI_QUIRK_TABLE entries keep their current
behavior without any schema change.
- lookup_pci_quirks_for_phase(info, phase) function that filters
by phase. lookup_pci_quirks(info) is preserved as a thin wrapper
around lookup_pci_quirks_for_phase(info, QuirkPhase::Enable) so
existing call sites keep working unchanged.
- load_pci_quirks_for_phase(info, phase) on the TOML loader side
with the matching wrapper load_pci_quirks(info).
Tests:
- redox-driver-sys target + host cargo check: clean (only
pre-existing libredox warnings).
- cargo test --lib: 80 passed, 0 failed.
Compatibility:
- PciQuirkEntry::WILDCARD constant preserves phase: QuirkPhase::Enable.
- lookup_pci_quirks unchanged for callers.
- All existing TOML quirk files keep their meaning (Phase::Enable
is the default in both directions).
This rounds out the v4.7 plan: Phase A (QuirkPhase::Early gating)
can land as a follow-up that filters by phase in the existing
driver-manager probe path. No behavior change for existing entries.
