mac_scsi / mac_NC5380

In mailine mac_scsi uses the generic NC5380 core, not the slightly modified copy mac_NC5380.c that someone created for it long time ago. Is it actually working that way in some tree? I'd love to get rid of mac_NC5380 if possible so we're down three from four slightly differrent "generic" NC5380 drivers.

If someone looked into porting the other drivers to main generic one that would of course be cool, especially as it got some major work from Alan lately and does proper looking, error handling, etc..

I had it working in the 2.2.x tree with the standard NCR5380.[ch] for PIO, but I was trying to get DMA working (for the IIfx) and had to make a lot of changes to properly support DMA. I never got the interrupt handling fixed, so I'm not sure if I actually fixed all of it. It didn't used to compile when configured to use REAL_DMA.

In fact, the 2.2 tree I have only has two different versions of the core 5380 support. The atari version has to add some hooks in odd places to make their DMA engine happy.

None of the trees I have checked out (2.2, 2.4, 2.6) actually seem to use mac_NCR5380.c, even if it is there, but 2.4 was never really supported for mac68k.

I'll try to look at mac_scsi again, but my list is pretty long now.
