Move GPIO mappings into a single module and select a board profile at process startup instead of at compile time: Build every GPIO-facing utility for every supported profile. At the same time, we remove support for the historical AIBOM board type since it's the only one using positive logic, the other three variants share the same electrical behavior. Run piscsi, scsimon, scsiloop, scsidump, or sasidump with -C=STANDARD, FULLSPEC, or GAMERNIUM. FULLSPEC remains the default. To select a profile for the systemd service, set PISCSI_CONNECTION_TYPE and restart the service.

.Nm
|
|
Performs a self-test of the PiSCSI hardware to ensure that the board is functioning properly. In order for this tool to work, a special loopback cable MUST be attached to the PiSCSI SCSI connector.

|
|
In addition to testing the GPIO signals, scsiloop will perform a self-test of the hardware timers that are built into the system on a chip (SoC).
