48d4303235 applied patch from pr port-next68k/6704: next68k zs driver formatting error 
zs driver needs to print a newline.

c96a4ad63d 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.

d3e627398e 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.

ba3bedf25e After some experimentation, now allow dma start alignment to be 4. 
Removed separate alignment constant for ethernet since it appears to
be unnecessary.

ea8f01b987 Continued experimentation on SCSI driver. 
Added nextdma_debug variable to control debug printouts in nextdma driver
when ND_DEBUG is defined.

db8bf6a623 Revamped DMA interface to unify chaining and non-chaining dma sequences. 
Updated ethernet driver to work with new interface.
Continue work on esp driver.

87cb8573e1 Finished changes to use UVM on next68k. 
Turn on UVM by default in GENERIC kernel.

277322402c 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

29d472f53d 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.

Inspired by PR #6090, from Matt Jacob.

84676442e2 Commented out some bus_dma code, until I can fix. 
(bus_dma.c needs sync with alpha port!)
Continued progress on scsi driver.
A couple of other compiler warning level of tweaks.

1e54ab4262 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.

3a5d43569e changed diagnostic panic into a printf since an unexpected condition appears 
to happen every once in a while.  (The DMA interrupt gets called w/o
