Sync with recent change made to bha.c by mjacob:
...
Cute buglet: you can end up with zero CCBs if there were no targets
seen by the adapter. Always leave a minimum so the adapter can
finish attaching- it may be there w/o targets for a reason.

In LBA mode, always use the `total capacity' count, rather than calculating
...
the capacity based on the c/h/s numbers. In fact, don't use the c/h/s
numbers for much of anything.
For ATA-4 drives or later, always use LBA mode, since it's now required.
Collectively, this allows >8GB disks (like the 12GB Bigfoot) to work.

From Robert V. Baron:
...
Compute the disk block addr at command queing time rather than exec time.
This fix a bug which could lead to data corruption on disk: when a command
was reexecuted after an error condition (from wdcunwedge), the partition
offset was re-added to the block addr, leading to a transfert at the wrong
disk block.
This should fix the problem reported by some laptop's users, where the
first disk read after a suspend/resume returned garbage.

Correct defifintion of the WDCE_MCR and WDCE_ABRT bits: they have been
...
inverted since the begining.
This doesn't change anything, as these bits are not used in the driver.

Do endian swaps where appropriate. This is currently dependent on 'BYTE_ORDER'
...
since the driver only supports little endian busses.

The "mi" TGA driver. It's still not of much use on anything but alpha
...
because it depends on initialization by the firmware.
Further, an mi mmap() is needed...

Add hooks to make exclusive hardware locking possible. This is necessary

to make the driver suitable for the atari falcon.

Read up to 32 bytes. The ESCC *needs* 8, and it doesn't hurt to leave some

Move the code to wait for carrier on a tty into a common function, since it

Well, I don't have a Cyclades board, but I needed the alpha kernels
...
to compile. I made the changes that seemed to make sense tracking the
shift from TS_WOPEN to tp->t_wopen- but they may be wrong. I wasn't
subscribed to tech-kern so I missed the discussion, and C. Hannum
was not particularly enlightening. Sorry if this isn't quite right.

Make zs_iflush not loop indefinitly. Some Mac PowerBooks lie about having
...
two SCC channels, and can get stuck in an infinite loop. This change
stops after flushing 4 bytes. Might need upping to 8 bytes if we support
85230 ESCC's.
