/*
* Support for earliest LSI53C1010 boards.
* Commercial chips will be fixed, and then the
* corresponding code will get useless.
*
* This option enables work-arounds for the experimental
* C1010 chips revision 0 to work in DT mode.
* Since, officially supported chips (B0 stepping and later)
* have been fixed, nobody, except driver maintainers,
* should ever needed this option to have been defined.
* This option and the code it addresses will be removed
* from the source in some later version of the driver.
* By the way, the 53C1010 B0 stepping (rev. 1) has been
* tested ok with Ultra3 DT data transfers using this driver,
* without these work-arounds being enabled.

* SCSI differential.
* SCSI High Voltage Differential support.
*
* HVD/LVD/SE capable controllers (895, 895A, 896, 1010)
* report the actual SCSI BUS mode from the STEST4 IO
* register.
*
* But for HVD/SE only capable chips (825a, 875, 885),
* the driver uses some heuristic to probe against HVD.
* Normally, the chip senses the DIFFSENS signal and
* should switch its BUS tranceivers to high impedance
* in situation of the driver having been wrong about
* the actual BUS mode. May-be, the BUS mode probing of
* the driver is safe, but, given that it may be partially
* based on some previous IO register settings, it
* cannot be stated so. Thus, decision has been taken
* to require a user option to be set for the DIFF probing
* to be applied for the 825a, 875 and 885 chips.
*
* This setup option works as follows:
*
* 0 -> HVD only supported for 895, 895A, 896, 1010.
* 1 -> HVD probed for 825A, 875, 885.
* 2 -> HVD assumed for 825A, 875, 885 (not advised).
