a1bffadb58 - Add hooks (just empty shells for now) for MVME-{162,167,177} models. 
- Use information obtained from the Bug in locore to make identifycpu()
  produce some slightly more meaningful output.

- Garbage-collect some left-over hp300-specific stuff.

6d0345fdb7 - Save the boot device info a little earlier in initializaion. 
- Use the Bug to find out what kind of machine we're running on, and
  Do The Right Thing, namely:

	- Set `cputype' and `mmutype' as appropriate.

	- Crap out if the kernel doesn't support the machine we
	  booted on.

- Add hooks for MVME-{162,167,177} models; just an empty shell to be
  filled in later.

- Use `MMU_68040' rather than `-2' when checking the MMU type.

399b0e0f68 - Use MVME "machine options" to associate MVME models with CPU 
options (a'la the hp300 port).
- Declare a "machineid" extern.
- Define constants for machineid, which match the Bug's idea
  of MVME model numbers.

2bc8c4e5c2 Merge in 4.4BSD-Lite -> 4.4BSD-Lite2 changes. (untested). 
The Lite2 changes  include:
  * Remove the last vestiges of high-bit-set-means-delay for output chars.
  * Handle the  2100/3100 having partial modem control on line 2 only,
    whereas the 5000/200 has modem control signals on lines 2 and 3.
  * Add RTS/CTS support for lines 2 and 3 on a 5000/200.
  * Add more s = spltty(); splx(s); where needed but not present.

 *	registers as specified in "regs"
 *	(for the flags, though, only these flags are passed to the BIOS;
 *	the remainder come from the flags register at the time of the call:
 *	(PSL_C|PSL_PF|PSL_AF|PSL_Z|PSL_N|PSL_D|PSL_V)
 *
 *	Fills in *regs with registers as returned by BIOS.

fda7345c98 re-implement BIOS trampoline as a more general-purpose, reusable trampoline. 
calling interface (via a grapple in locore.s) is:
/*
 * void bioscall(int function, struct apmregs *regs):
 * 	call the BIOS interrupt "function" from real mode with
 *	registers as specified in "regs"
 *	(for the flags, though, only these flags are passed to the BIOS;
 *	the remainder come from the flags register at the time of the call:
 *	(PSL_C|PSL_PF|PSL_AF|PSL_Z|PSL_N|PSL_D|PSL_V)
 *
 *	Fills in *regs with registers as returned by BIOS.
 */

still some generalization to do (moving this to a better named location,
cleaning up #if tests from NAPM > 0 to something else to allow easy
sharing by other drivers)

Thanks to Charles Hannum for complaining about the previous BIOS grapple
and inspiring me to hack this one together.

1. Start at the specified entry instead of entry 0.

3. Don't use the starting index again for storing the saved entry - the cmap
   pointer was previously initialized using the starting index.  This fixes

   set the color map (usually by the X server).

2a73ef60b7 change cfprint_t type definition to take a const char *, rather than 
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).

7dff0aa247 After servicing an interrupt, check to see that there's not another 
one pending before we clear the interrupt flag.  This avoids a condition
where the line appears to go catatonic (which is particularly easily
triggered by pppd).  From Bill Studenmund <wrstuden@loki.stanford.edu>.
XXX - we should probably log this if it gets excessive.

7b8910c01d Vastly simplified the FPE stubs code now that there are labels for all the 
core entry points. i.e. the linker does the work rather than the stub code.
Optimised transferring the trapframe between UND32 and SVC32 mode stacks
in the fpe_post_proc handler.
Added experimental code to handle must of userret in UND32 mode. This means
that the copy of the trapframe and the switch to SVC32 mode is only needed
if mi_switch() has to be called. (This saves a vast number of pointless
trapframe copies).

3142731d09 Re-written FPE core header. 
Added branches relative to the start of the module and labels to the various

All other offsets are now relative to _fpe_arm_start.
