It's probably not really a compiler bug- somebody pointed out
that it was the kernel making strings readonly. But I do think it's
a bug. The actual code was really more like:
char *revname;
...
revname = "2X00";
...
revname[1] = '2'; <<<<<<<<< BOOOM
The variable revname is not a const. If I had said
const char *revname = "2X00"
...
revname[1] = '2';
that would indeed be breaking const rules.
char *foo = "XXXX";
...
foo[1] = 'Y';
blow up (in the kernel) with the 2nd assignment. Work around it here-
it's probably just as well- I was spending more in cpu instructions doing
the assignment than I was saving in string space (it would have been
cheap on a pdp11 or a 68k- but the address loads and assignments on something
like sparc or alpha way outweigh the savings in space. Tsk.).
change I didn't take is the %llu format- I can't have a common
across multiple platform module assume a %ll argument capability-
which really pointed out that I shouldn't be trying to *print*
something which could long long.

Also, adjust message/command construction in ncr53c9x_select() to work no
matter how the structure alignment works out (needed at least for m68k).
Tested by me on mac68k & alpha, and sanity-checked by eeh.
Though ifconfig -m no longer show 5Mbps/11Mbps for PC4500 by this fix,
I cannot find how to set fixed transmit speed to the firmware.
FreeBSD version of driver apparently ignore the value set by ancontrol(8).
This is very adhoc work for IETF meeting.
- Since it seems that 'an' and 'wi' have similar hardware, low level
functions should be shared.
- There are PCI/ISA cards of Aironet but not supported yet.
- The wiconfig interface is changed so that wiconfig cannot be used.
- 'ancontrol' of FreeBSD is not ported.
- Only infrastructure mode is tested.
- WEP is not supported.
Though I only have an Aironet card, Cisco card should be expected to work.
The intent was to protect the full range of ports on the board by the
barriers. But the start address was wrong. Fix it.
While here, change two other barriers to also protect the full range
(not only the nic ports), and add yet another similar barrier.
quite simply a question of the Qlogic being little endian and having
to have stuff swapped on big endian machines- it also has to do with the
fact that the SBus and PCI DMA layouts are wierd with respect to this.
At any rate, now finally fixed- works on Mac G4, tested it on a SS10
for sparc, checked on alpha to see if I've broken anything, and as
soon as I get another spare afternoon I'll finally install a sparc64
version which should just work (as it'll be like the Mac).
(comsoft() can be invoked before comopen() on serial consoles; a character
received before the console is opened "for real" can result in a fatal trap
unless the ring buffer pointers are initialized early)
wdc drivers (like macppc's obio IDE interface) can use it. Also add
support to both wd attach line and to wdc_print_modes() to print
Ultra/{33,66,100} for respective UDMA modes (From Manuel Bouyer).
* support devices that crash when reading the codec registers; a flags
interface is added to the host interface and one flag is defined
(AC97_HOST_DONT_READ).
* new API (restore_ports) for restoring the user's settings. This
can be useful after an APM resume after a suspend to disk.

- move status handling in siop_scsicmd_end(), it's better than in siop_intr()
- define 2 internal SIOP status, for "no status reported by device" and
reset condition
- add a list of "urgent" command, to be executed before the list of command

by a QUEUE FULL and have to be requeued in order.

Snapshot of work in progress on tagged queuing: we can send/receive

Also fix egregious bug where we would never decrement
the islocked recursion counter. I guess this means
that we don't recurse on this platform! All of this should
go away when we have real lock primitives to use in drivers.

member is added to the tulip_softc to limit the maximum burst length.
This member defaults to zero which means no restriction for burst length.

VGA_CONSOLE_SCREENTYPE because the screen types are hardware specific
