Update of /cvsroot/src/sys/arch/mac68k/mac68k
In directory netbsd1:/var/slash-tmp/cvs-serv846

Modified Files:
        machdep.c 
Log Message:
Sync with current 040-related development:

 - Combine initenv() and getenvvars().
 - Hardwire some PowerBook internal video addresses, from Takashi Hamada.
 - When printing out the machine model/CPU, use the new cputype variable
   instead of the Booter's PROCESSOR environment variable.
 - Use new ptest040() function code argument (though for now, the MMU is
   disabled on the 040).
 - Revert previous change in get_physical() that seems to have broken
   some machines; use an ADD instead of an OR when determining the PA.
 - Some (very minor) style cleanup of asm code.

Update of /cvsroot/src/sys/arch/mac68k/mac68k
In directory netbsd1:/var/slash-tmp/cvs-serv1202

Modified Files:
        locore.s 
Log Message:
Sync with current 040-related development:

 - Figure out what CPU we have, rather than assuming the Booter knows,
   and set cputype variable accordingly.
 - Carefully rearrange the order of various MMU/ATC operations so as to
   eliminate possible side effects.  Also, re-order the initial bootstrap
   code to make clear what various sections of this code do.
 - Adjust to combined initenv()/genenvvars() (the latter has assimilated
   the former).
 - Add a function code argument to ptest040().
 - Use symbolic constants from assym.h where appropriate (and defined).
 - Some style cleanup.

Update of /cvsroot/src/sys/arch/mac68k/mac68k
In directory netbsd1:/var/slash-tmp/cvs-serv1768

Modified Files:
        locore.s 
Log Message:
Use only FC $1 in TT0 in get_pte(), and map the entire address space.  We
can then access the page table entries directly using user data space with
the MOVES instruction.  This should resolve the problem on the Duo 2x0
series with hard hangs in this function.

Warning:  do not call any function that accesses user data space (FC $1)
from get_pte()!
