ncrsc —
NCR 53c710 SCSI I/O Processor
The ncrsc driver provides an abstraction layer between
the SCSI hardware fitted to Motorola MVME167 and MVME177 single board
computers (NCR73C710), and the machine independent SCSI drivers described in
scsibus(4).
In addition to sending the required SCSI commands to target
devices on the SCSI bus, the ncrsc driver deals with
DMA, device interrupts, sync/async negotiation and target
disconnects/reconnects.
The current ncrsc driver should be obsoleted and
replaced with a machine independent version.
