Rung 1 (ownership): a default-off gsp_phys_gpu module param; on claim the
distribution driver is released from 10de:1ed3, our pci_driver binds it,
BAR0/1/3 are mapped and the falcon state is sampled; release unbinds ours
and rebinds the distribution driver. Verified live: claim reads
BOOT0=0x164000a1 with the falcon halted and mailboxes clear; rmmod rebinds
nvidia and nvidia-smi stays healthy.
Rung 2 (firmware): while the device is owned, gsp_phys_fw (default
nvidia/570.211.01/gsp_tu10x.bin) is fetched with request_firmware, checked
as ELF64 RISC-V, and its sections are logged (.fwimage, .fwversion,
.fwsignature_tu10x). The image is held for the boot rung.
The claim is default-off; the emulation path is unchanged.
