Create a set of MMC_RSP_xxx definitions which correspond to the
response type we expect at a high level.  These are created from
a set of flags; a MMC host driver can either interpret the flags
as the high level response type, or the low level individual
flags.

When we are nearing the end of a transfer from the card, we may not
have sufficient data in the FIFO to trigger a "half FIFO full" IRQ.
Therefore, when we have less than MCI_FIFOSIZE bytes left, switch to
"FIFO contains data" IRQ mode instead.

This allows us to transfer a whole request for multiple pages in one
transaction with the MMC card, resulting in higher overall throughput.

This is in preparation for SG data IO.

Prevent IRQ race conditions between the two handlers and within the
primecell itself.  Unfortunately, the primecell does not always mask
the FIFO empty interrupt we reach the end of a transfer to the card.
Also, we may receive the "data end" interrupt prior to finishing a
transfer from the card, so mask this off until we've read the last
bytes from the FIFO.

- Use mmci_stop_host() to ensure that the data FSM is shut down and
  any driver held data is properly released.
- FIFO size is 64 bytes not 16.

Pass the total number of MMC data blocks in the request to the
host driver.  Since existing MMC host drivers do not support
scatter-gather at present, the block queue defaults have been
chosen to prevent scatter-gather block requests for MMC.  A
host can alter these parameters when it wishes to take advantage
of SG capabilities.

Allow MMC host drivers to specify their data phase capabilities
to the block queue.  This will eventually allow us to perform
SG data phase operations, thereby processing a single request
in one go.

Fix of the debug/trace driver and removal of irq locks.

 - Only spinlocks[bh] are used now.
 - Removed obsolete direct debug /proc interface.
 - Update of internal trace features and its API.
 - Use common definition of MAX_DESCRIPTORS.

Some time ago, I sent on this list a mail about my strange problem with my
SiS900 network card (Subject was Sluggish performances with FreeBSD)

To sum up, when my card is in 100Mb mode, I have poor throughput but in
10Mb, all seems normal.

After some tests, it seems these results was due to a misdetection of the
PHY device.  mii-tool reports :

 product info: vendor 08:00:17, model 3 rev 0

and after some search on the web, I found it's a NS DP83847 which is very
similar.

Some interfaces (notably PCMCIA ones) don't decode the master/slave select so
you get two copies of a device appearing and bad things happening if a user
accidentally uses both. 

This checks for the model/serial matching but also knows about non ATA drives
ide=noprobe and a Maxtor problem that was found in Andrew's testing of an
earlier patch. Although M00000.. drives should be RMA'd to Maxtor (and with
info on where they were obtained...) we don't want to break anyone who has
them.

If you get invalid geometry (eg a failed drive) the box hangs on boot because
we try and unregister the registered driver and end up in a locking mess.

We change the behaviour to simply leave the device unattached which avoids
the mess.

This was put in for PPC specifically and defined in the 2.4 tree to be
paranoid about breaking stuff. The actual wait for hwif spin up is however
perfectly correct for all drives. In the normal PC case the PC BIOS has done
this but with other embedded boxes and with things like LinuxBIOS it may not
have done. Thus it should always be done.

As noticed by Alan Cox:

"It doesn't work now so it clearly isnt being used 8). We hold the lock
because its a proc function and we then replace the proc functions in the
attach method -> deadlock. It is also incredibly hard to fix without a
major rewrite."

The same is true for HDIO_SET_IDE_SCSI ioctl.

Both were broken 18 months ago in 2.5.63 as a side-effect of locking fixes.

Let's leave the code for a while yet, and see if somebody screams.
But both Red Hat and SuSE claim it is unused, so it probably is. The
driver hasn't gotten updated in years, and google doesn't seem to
show any usage either.
