+description: |
+  PCI function zero owns the shared N1 firmware bootstrap. The boot producer
+  supplies the personalized FTAB filename and packed firmware platform ID.
+  The endpoint must be left in its stopped ROM personality with DMA and MSI
+  quiesced. A supported APIF PCI host performs the isolated port reset after
+  ROM bootstrap. This binding does not authorize adopting an existing live
+  firmware session or releasing another owner's retained DART streams.
