* devices/machine: simplified more handlers (nw) Ivan Vangelista2020-03-251-2/+2

* nscsi_bus: Class overhaul (nw) AJR2019-07-111-0/+1
| | | | | | - SCSI slot options are no longer required to implement nscsi_device themselves. Instead they implement nscsi_slot_device_interface, which contains a finder for a nscsi_device. This is to accommodate LLE SCSI drives with their own LSI interface chips. - SCSI bus device connection is now done through device_resolve_objects rather than device_config_complete. (The pessimized code to access the device finder is because that will not have been resolved yet.) - Added a validity checking method for nscsi_connector.

| | | | | | | | | | | | | This effectively reverts b380514764cf857469bae61c11143a19f79a74c5 and c24473ddff715ecec2e258a6eb38960cf8c8e98e, restoring the state at 598cd5227223c3b04ca31f0dbc1981256d9ea3ff. Before pushing, please check that what you're about to push is sane. Check your local commit log and ensure there isn't anything out-of-place before pushing to mainline. When things like this happen, it wastes everyone's time. I really don't need this in a week when real work™ is busting my balls and I'm behind where I want to be with preparing for MAME release.

Very WIP status and some obvious issues, but working well enough to load RISC/os.
