bb47e5aecf Increase some DELAY(), this seems required on some hardware (I'm not sure if 
the hardware is at fault, or if DELAY(1) waits for less than 1us).
Improve debuging messages for wdcreset_wait().

d5a261206d Replace the #ifdef'ed variable DELAYs with a pair of non-ifdefed 
DELAY(1)'s. This should fix interrupt driven lpt driver hang and
reboot problems for the group of users who have experienced them, and
shouldn't hurt anyone else.

85ad0d175c Fix bogons in previous change: 
* The fact that IIR_NOPEND was not set on entry does *not* mean that no
  transmission was in progress.  Besides, we don't want to throw away receive
  interrupts either.
* In the !clearirq case, we didn't splx().

6a228da053 Mods to com_common_putc(). When doing kprintf() or kgdb output: 
1. don't clear the irq unless it was clear before transmitting
2. also do various bus_space_barrier() ops
Stops console from freezing when kprintf interrupts tty driver output.

ad69d389ab Remove the hack to attach devices responding with ATA signatures as atapi if 
IDENTIFY said so: it doesn't help for the drive this was supposed helping,
and seems to break another device.
In interrupt routine, don't return 0 if we are polling: this should fix the
"panic: wdc_exec_command: polled command not done" some people reported
(kern/7269).

1ff88ee466 Avoid busy-waiting when possible if we are not polling (real IRQ or timeout 
callback). Shared PCI IRQ should now work (but still untested).

8ade3b61ba Add two #ifdef BROKEN_LPT_DELAY's in to the central write byte 
& strobe cycle. These bracket DELAY()'s of BROKEN_LPT_DELAY
microseconds. This can be used to kludge around mysterious hangs and
reboots some users experience. The cause of these failures is still
not known, but is conjectured to be hardware bug originated failures
in the bus cycle.

1c99e4196a Use BUS_SPACE_ALIGNED_POINTER() instead of ALIGNED_POINTER() where the pointer 
in not just used to access memory but is bassed to bus_space_xxx_n()
methods. For debugging purposes, bus_space can have additional constraints
which will be properly met by BUS_SPACE_ALIGNED_POINTER().

69d2d27c1b Use bus_space tags and handles, embedded in MD hooks AM7930_{READ_WRITE}_REG 
to handle MD delay and bus padding. Tested on sparc2 by David Brownlee.

Should use regmaps, but that breaks sparc pDMA assembly code.

a6365676fa Add a new disk flag: DRIVE_OLD for pre-ATA disks. probe routine will now set 
DRIVE_OLD, DRIVE_ATA or DRIVE_ATAPI based on register signatures.
The attach routine will issue a IDENTIFY command for ATA/ATAPI disk,
to detect flase matches by the probe routine.
probe/attach should now be fully compliant with ata-4/ata-5. As a side
effect, ATAPI drives which improperly use ATA register signatures should now
be attached as ATAPI.

ba74f49e60 Keep track of CRC errors in Ultra-DMA mode. If we noticed a CRC error and we 
need to downgrade, downgrade to PIO, as it has been shown if we got CRC errors
in Ultra-DMA mode, we will have silent data corruption in multiword DMA mode
(isn't IDE wonderfull ? :).
Set timeout to 1s for "normal" ata I/O, to minimise the effects of missed
interrupts.
