1761 This is a core driver for NCR53c9x based scsi chipsets,
1762 also known as "ESP" for Emulex Scsi Processor or
1763 Enhanced Scsi Processor. This driver does not exist by
1764 itself, there are front-end drivers which, when enabled,
1765 select and enable this driver. One example is SCSI_SUNESP.
1766 These front-end drivers provide probing, DMA, and register
