+ help
+ 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,
+ select and enable this driver. One example is SCSI_SUNESP.
+ These front-end drivers provide probing, DMA, and register
+ access support for the core driver.
