DMA, not dma nor Dma.

Add trailing ; to CFATTACH_DECL.

Use CFATTACH_DECL().

Declare all cfattach structures const.

Statements must follow labels.

Implement mstohz() as discussed on tech-kern, and use it in SCSI drivers
to convert xs->timeout to callout() parameter.

bcopy/bcmp/bzero -> memcpy/memcmp/memset

Implement bus_dmamap_sync properly.
dma_cachectl is now used only for DMAC array chain.

Ooops, previous commit removed an important line unintentionally.

Remove unused variables.
Correct printf format strings.

Use common macro to check message length.

Pull up the thorpej_scsipi branch to main branch.
This is a completely rewritten scsipi_xfer execution engine, and the
associated changes to HBA drivers. Overview of changes & features:
- All xfers are queued in the mid-layer, rather than doing so in an
ad-hoc fashion in individual adapter drivers.
- Adapter/channel resource management in the mid-layer, avoids even trying
to start running an xfer if the adapter/channel doesn't have the resources.
- Better communication between the mid-layer and the adapters.
- Asynchronous event notification mechanism from adapter to mid-layer and
peripherals.
- Better peripheral queue management: freeze/thaw, sorted requeueing during
recovery, etc.
- Clean separation of peripherals, adapters, and adapter channels (no more
scsipi_link).
- Kernel thread for each scsipi_channel makes error recovery much easier
(no more dealing with interrupt context when recovering from an error).
- Mid-layer support for tagged queueing: commands can have the tag type
set explicitly, tag IDs are allocated in the mid-layer (thus eliminating
the need to use buggy tag ID allocation schemes in many adapter drivers).
- support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command
will be requeued, or a REQUEST SENSE will be sent as appropriate.

Hopefully this is a temporary fix; something might be missing in
the SCSI negotiation.

New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

Do not reset SCSI bus.

Update for SCSIPI changes.

Do not memcpy to the bouncebuffer in datain.

Shut up gcc -Wall.

Use bus_dma(9) for DMA bouncing.
The code is dirty. It should be rewritten in the future.

Merged minoura_x68k_bus_h branch.

Issue SCSI reset on initialize.
Clean unused mha_reset.

Update HBAs to incorporate the new max_lun property.

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.
