Fix return value in interrupt routine so that dma gets flushed correctly.
...
Turn on the esp_match since polling the scsi bus now works.

Continue work on scsi driver. Added tail dma buffer. Still non functional.

Fixed dma instability introduced with nextdma.c rev 1.7
...
This fix removes putting 0xfeedbeef in the unused restart registers.
When that was done, the machine would panic after a short while
with 0xfeedbeef in the normal dma buffer registers. A restart
cycle is probably hapenning without an interrupt or something.

applied patch from pr port-next68k/6704: next68k zs driver formatting error
...
zs driver needs to print a newline.

Continued work on esp driver. Now successfully identifies a scsi target.
...
Unfortunately, to get dma to work, we have to align past the end of
the buffer, which smashes other variables on the stack.
match function still disabled, as it isn't ready yet.

changed register for start of dma buffer to be DD_NEXT_INITBUF instead
...
of DD_NEXT for regular dma transfers, and not just ethernet transmit.
Keep track of dma read/write direction and set it each time we start or
restart dma. This allows scsi to work, and doesn't appear to hinder ethernet.

After some experimentation, now allow dma start alignment to be 4.
...
Removed separate alignment constant for ethernet since it appears to
be unnecessary.

Continued experimentation on SCSI driver.

Added nextdma_debug variable to control debug printouts in nextdma driver
when ND_DEBUG is defined.

Continue work on esp driver.

Sync'ed more files and routines with mvme port in prepartion for UVM.

Now use generic m68k cachops everywhere rather than defining them in locore.s

Garbage-collect the open_target_lu and close_target_lu entry points from

struct scsipi_adapter; they were not used.
Add a scsipi_ioctl entry point to struct scsipi_adapter. This will be
used to issue ioctl commands to the host adapters.

Reserved 8k at top of memory for ROM. This fixes warp9c boot problems.

changed ethernet panic to a warning when out of DMA buffers. This allows
resuming if you sit in ddb too long.
