Supports some 53C8XX chips but not 7XX chips.
Does not support, in particular, the following features:
- Tagged Commands
- Wide SCSI
- On-chip RAM for SCRIPTS.
- PCI cache-line optimizations.
...
Is very 7XX/8XX generic and so can be hacked easily to support old 7XX
chips.
Note, that if I ever think it is worth it I may support at least 720/770
chips for EISA in the ncr53c8xx driver.
For 710/ISA there is no chance at all. Just thinking that DMA is performed
through the ISA/BUS disqualified the thing.

It seems to be able to. You have to implement the detection routine for
your platform. It should support little-endian too.
