particular, make sure that all the SIASTAT_ANS bits are in the right state
so we don't do something inane.
Still doesn't actually bring the link up properly, but at least it negotiates
most of the time, and does it a little faster.
1) Do not call tlp_sia_update_link() in Nway mode, and do not look at SIASTAT
in any other place that nway_status(), where we first check that it's valid.
In other places, look at IFM_ACTIVE after having call nway_status().
2) Eliminate stupid MII_MEDIACHG calls, and arrange for nway_service() to
update status on every call.
3) Nuke the synchronous case of nway_auto() from orbit.
4) Do not call nway_statchg() when using manual configuration; tlp_sia_set()
does everything we need.
1) Set OPMODE_TTM in the default tsti_opmode, so that nway_status doesn't
blow up and report the wrong media type when statically configured. (This
code is a hack.)
2) Do not set IFM_ACTIVE (i.e. ignore SIASTAT_LS*) when in auto-negotiation
mode and negotiation has not completed (per 21143 manual).
3) Do not clear auto-negotiation mode; otherwise the chip will not
renegotiate on a link failure.
With these changes, 10/100 selection is more stable, and auto-negotiation
comes up with the right status and detects link, but the link does not work
unless it's hardwired. More work is needed.
to schedule clock interrupts at a fixed interval, rather scheduling
the next one based on the time of the arrival/servicing of the previous
clock interrupt. Also, pick up a trick from the sbmips port to convert
a division in ip22_clkread to a multiplication, since those are much
cheaper -- the details of that are described in Simon's commit (see
Message-Id: <20020306073437.1D2A8B004@cvs.netbsd.org>). Thanks to
Jason Thorpe and Dominic Sweetman's "See MIPS Run" (where I found
mention of this very subject while looking for something totally un-
related! 8-) for the clue about the source of the timekeeping problems.
For the IP32, where we have no clock-calibration code yet, use the CPU
frequency provided by ARCS instead; it beats a hard-coded value!
As an added bonus, most of the CPU-clock related stuff is now collected
together in cpu_info_store, rather than as a collection of unorganized
global variables.
Obsolete NBUILDJOBS; build.sh just passes -jN through to make(1),
which inherits it cooperatively through the build tree. Fix
documentation so that it's shown to be deprecated.
If you use build -jN, please save full build logs so that errors due
to missing dependancies can be analyzed and corrected.
