(we need to make them signed to spot controller overruns), and fix format
strings accordingly.
While there, make sure every runtime printf is prefixed by either the complete
target information, if available, or at least the driver name with the
proper instance number - supported systems with > 1 wdsc are quite common.

timeout', instead of being stuck with a non-progressing request. This lets
the nonexistent LUNs of the Insite Floptical probe (as non-existing)
correctly.
Step two of Floptical support, now if only the loading mechanism would unjam
I could try some real I/O with it...

if their size is not exactly six bytes, as the chip can't cope with this
situation.
Another situation all 33C93 do not cope with very well, is sending stop
commands to targets (such as all sd(4) devices when halting with poweroff) -
it takes a very long time to recover once all targets on the bus have been
powered down, so we need to raise timeouts to unholy values (one test case has
required more than 20 seconds to recover). Not surprising, as this command
is not documented as supported in the chip documentation.

(IP20, IP22, IP24) in 64-bit mode, adapated from NetBSD. Currently limited
to headless operation, input and video drivers will get ported soon.
Should work on all R4000, R4440 and R5000 based systems. L2 cache on R5000SC
Indy not supported yet (coming soon), R4600 not supported yet either (coming
soon as well).
Tested to boot multiuser on: Indigo2 R4000SC, Indy R4000PC, Indy R4000SC,
Indy R5000SC, Indigo2 R4400SC. There are still glitches in the Ethernet driver
which are being looked at.
Expansion support is limited to the GIO E++ board; GIO boards with PCI-GIO
bridges not ported yet due to the lack of hardware, and this kind of driver
does not port blindly.
Most of this work comes from NetBSD, polishing and integration work, as well
as putting as many ``R4x00 in 64-bit mode'' erratas as necessary, by yours
truly.
More work is coming, as well as trying to get some easy way to boot install
kernels (as older PROM can only boot ECOFF binaries, which won't do for the
kernel).
