58d4f7ae24 Add support for future PicassoIV's which use an autoconfig space of 64MB. 
The framebuffer base address is then at a different offset.
The patch is from Klaus Burkert.

a02a989bcf The 53c720 and up are really different. For example, the method to determine, 
when disconnecting etc., how much data were transferred, has changed.
Symptom: SIOP invalid instructions when doing data transfers to disks that
disconnect.
XXX The bits etc. need to be defined correctly in the siopreg.h file, and
symbolic values used.

263d2c47a5 Read-only unnmanaged pages on MIPS3 need the RO attribute bit, otherwise the 
tlbmod exception panics.  This appears to have been incorrect even in the pica
pmap.c, which I pulled in for the pmax.  Fixes Xcfbpmax crashes on R40x0
systems with sfb framebuffer.

Fix resident_count tracking so it doesn't go negative.  UVM will change a
page mapping without removing the original mapping.  That was causing a
problem early on when getting UVM working on the mips, and the explicit
pmap_remove() done by pmap_enter() was decrementing the resident_count.
Do the pmap_remove() first, then check if the current mapping is not valid
and increment the resident_count.

07304bd858 On multiprocessor systems, it is possible that a lev1map might be in use 
by two processors concurrently.  This means that we cannot modify the
lev1map in use by the processor which wishes to use the PROM.

Fix this by creating a separate lev1map for PROM users.  This lev1map
is a copy of the kernel_lev1map, with the exception of the necessary
PROM mapping.  When a processor wishes to use the PROM, it switches
its PTBR to point at the prom_lev1map, performs the PROM operation,
and switches back to its previous lev1map.

Note that kernels without multiprocessor support use the old method
of modifying the current lev1map.

Also, serialize access to the PROM via a spin lock.

76e4555f2c Now that we have the kthread mechanism, massively clean up the way 
additional processors are spun up on multiprocessor Alpha systems.
Now, each processor gets its own idle thread (the primary processor
uses proc0).  This idle thread is used in switch_exit(), rather than
explicitly referencing proc0.

Also, make `curproc', `fpcurproc', and `curpcb' per-cpu values.  This
required some data structure rearrangement; cpu info is now statically
allocated in the BSS, rather than via malloc(), and cpu_softc is gone.
(Modeled somewhat after NetBSD/sparc's multiprocessor info structures.)

b4a33c4e60 Scheduler bug fixes and reorganization 
* fix the ancient nice(1) bug, where nice +20 processes incorrectly
  steal 10 - 20% of the CPU, (or even more depending on load average)
* provide a new schedclk() mechanism at a new clock at schedhz, so high
  platform hz values don't cause nice +0 processes to look like they are
  niced
* change the algorithm slightly, and reorganize the code a lot
* fix percent-CPU calculation bugs, and eliminate some no-op code

=== nice bug === Correctly divide the scheduler queues between niced and
compute-bound processes. The current nice weight of two (sort of, see
`algorithm change' below) neatly divides the USRPRI queues in half; this
should have been used to clip p_estcpu, instead of UCHAR_MAX.  Besides
being the wrong amount, clipping an unsigned char to UCHAR_MAX is a no-op,
and it was done after decay_cpu() which can only _reduce_ the value.  It
has to be kept <= NICE_WEIGHT * PRIO_MAX - PPQ or processes can
scheduler-penalize themselves onto the same queue as nice +20 processes.
(Or even a higher one.)

=== New schedclk() mechansism === Some platforms should be cutting down
stathz before hitting the scheduler, since the scheduler algorithm only
works right in the vicinity of 64 Hz. Rather than prescale hz, then scale
back and forth by 4 every time p_estcpu is touched (each occurance an
abstraction violation), use p_estcpu without scaling and require schedhz
to be generated directly at the right frequency. Use a default stathz (well,
actually, profhz) / 4, so nothing changes unless a platform defines schedhz
and a new clock.  Define these for alpha, where hz==1024, and nice was
totally broke.

=== Algorithm change === The nice value used to be added to the
exponentially-decayed scheduler history value p_estcpu, in _addition_ to
be incorporated directly (with greater wieght) into the priority calculation.
At first glance, it appears to be a pointless increase of 1/8 the nice
effect (pri = p_estcpu/4 + nice*2), but it's actually at least 3x that
because it will ramp up linearly but be decayed only exponentially, thus
converging to an additional .75 nice for a loadaverage of one. I killed
this, it makes the behavior hard to control, almost impossible to analyze,
and the effect (~~nothing at for the first second, then somewhat increased
niceness after three seconds or more, depending on load average) pointless.

=== Other bugs === hz -> profhz in the p_pctcpu = f(p_cpticks) calcuation.
Collect scheduler functionality. Try to put each abstraction in just one
place.

2426418d47 More work on Tseng support. Now both my et6000 _and_ the et6100 work. I just 
whish that programming MDRAM latency values came out of the BlackMagic(tm)
domain :-(

cb2e02af94 Make this compile and work again after the assembler update. 
The new assembler doesn't allow 16-bit relocations involving arithmetics
with 32-bit variables. (The old one did silently truncate, which was
the right thing in our case.) Further, the new assembler uses to scatter
size prefixes around if the size of the operation is not explicitely
specified, even if the result is nonsense, eg for moves to segment
registers or control registers.
Add some debugging code (generating printouts) and comments.
Remove the !BOOTROM code which was intended for a DOS harness but isn't
that useful anymore.
Some cleanup and formatting to make it more similar to the other
startup code variants.
