the Booter Loader loads and\nstarts that firmware into the GSP, making it run in RISC-V mode.\n\nThese operations need to be reverted upon unloading, particularly the\nWPR2 secure region creation, as its presence prevents the driver from\nsubsequently probing.\n\nThus, load and run the Booter Unloader and FWSEC-SB firmwares at unbind\ntime to put the GPU into a state where it can be probed
