- This is a core driver for NCR53c9x based scsi chipsets,
- also known as "ESP" for Emulex Scsi Processor or
- Enhanced Scsi Processor. This driver does not exist by
- itself, there are front-end drivers which, when enabled,

This is the driver for the Sun ESP SCSI host adapter. The ESP
chipset is present in most SPARC SBUS-based computers.
