the platform supplies a clkread function that does something other than
return 0 (which is the default unless overridden by the platorm code).
Supply such a function for the IP22; even if it isn't perfect, it goes
a long way to making ntp usable.
While I'm at it, move the ticks-per-hz variable out of the struct platform
since it's really private to the per-platform interrupt/clock code.
XXX: No clkread function supplied for IP32, since it has other problems --
like a hardcoded ticks-per-hz, but the same code as on the IP22 could be
used.
* Define a CPWAIT macro as described in the i80200 manual and use it,
rather than replicating the code in a few places.
* The i80200 manual notes that the line-allocate operation used to
do global D$ clean does not actually perform a load/fill request
from external memory, and thus does not actually place valid data
in the cache lines allocated. Require that machine-dependent code
allocate an appropriately-sized chunk of unmapped VA space for the
global clean operation in order to avoid unpredictable results.
* The i80200 manual notes that the VA range for the Mini-Data global
clean (which *must* be mapped to physical memory) must be reserved
exclusively for cleaning the Mini-Data cache. Require that machine-
dependent code allocate an appropriately-sized chunk of memory for
this purpose.
pages, we use the standard (4K) page size as PAGE_SIZE. Make the
PAGE_SIZE related variables compile-time constants that reflect this.
Results in a bit over 2K worth of .text savings, and visibly better
code in the places that use PAGE_SIZE, etc.

and fix one spelling nit.
Mostly from port-hp300/8824, which had already pointed out
y2k (and y2k+1) bugs before 2000, but they were not fixed
till the last month. (I noticed this PR today. Oops)
use the file system time. (My iMac seems to give 1904 as the year very
often (dead battery?), and setting the correct date with ntpdate doesn't
seem to work.)
due to its similarities.
Patch has been tested by many people on the sgimips list for some time with
no complaints.

- Full support for SCSI-2 Tagged commands (enabled by default)
- Implement save and restore datapointer messages
- Formalize interface between MI and MD drivers.
- decouple interface between MD driver and DMA routines
- Use scsipi layer where appropriate (Tags, Sync Negotiations etc)
- control blocks stored using kernel pool(9) functions
- evcnt(9) compliant counters
- Enable advanced features on later WD33c93 chips.
(Identify message out phase is hardware assisted)
- Improved timeout support (one per active control block)
- Improved MESG_IN and MESG_OUT handling
- Start to tidy up debugging output
- Numerous bug fixes and cleanups throughout
Changes are based largely on the NCR53c9x MI driver for ideas on
how to DTRT.
DMA via the Secondary Inbound window, for now. Will probably
need to revisit this at some point.
Require that the board-specific i80312 front-end slice off a
subregion for the memory controller before calling i80312_attach(),
and fix a bug in the IQ80310 front-end that caused the Secondary
Inbound window to be configured incorrectly.
While I'm here, bump RAWFS_BSIZE up to 8192 since the installation
instructions use "bs=8k oconv=sync". My Archive Viper now streams
nicely while booting.
