on indirect-config busses a (permanent) softc that they could share
between 'match' and 'attach' routines:
Define __BROKEN_INDIRECT_CONFIG so that old autoconfiguration
interfaces are used, until drivers are converted to use the new
interfaces (actually, converted back to use the _older_ interfaces)
which prohibit indirect configuration devices from receiving a softc
in their match routine that they can share with their attach routine.
* Move mips-I pte (TLBlo) definitions from pmax/include/pte.h
to mips/include/mips1_pte.h
* Move mips-III pte (TLBlo) definitions from pica/include/pte.h
to mips/include/mips3_pte.h
* Add new mips/include/pte.h, which includes exactly one of
mips1_pte.h or mips3_pte.h (which still have namespace collisions),
depending on "options MIPS1" or "options MIPS3". (hack).
Move soft kvtopte(), ptetovk() definitions to mips/include/pte.h
* Add macro PTE_TO_PADDR() to hide the different hardware TLB formats
when mapping from pte to physical address.
* Add macro PTE_READONLY() to hide lack of SW read-only bit in mips-III
tlb. (mips1 pmap uses a sw bit in the PTE, mips3 looks up RO bit in
the kernel pmap.)
* Use macros (not direct TLB frobbing) in mips/trap.c, to make it
mips-1/mips-III indepenndet.
* Change {pmax,pica}/include/pte.h to just do #include <mips/pte.h>.
consistency with the way machdep headers for other things are done.
(the creation of the ecoff_machdep.h files was done on the CVS server, to
keep the RCS logs intact.)
macros to use to remove #ifdefs from the machine ID case check.
Eventually, these headers will contain other information, e.g.
machine-dependent relocation information, etc.
an vector (struct) of function pointers. Add prototype declarations for
each vector entry.
Add declarations for the r2000 (MIPS-I) and r4000 (MIPS-III) locore
versions of the relevant functions.
* add "MIPS_3k_" for the MIPS-I r[23]000-specific register definitions.
* add "MIPS_4k_" for the MIPS-II/III r4000-specific register definitions.
* add #defines that provide the old values for locore and user
code, so the existing code continues to compile.
Regression-tested against the old headers by grepping for #define's,
editing out the defined symbols, and preprocessing with both the previous
machConst.h headers and this version.
Some unused symbols (CPU and FPU must-be-zero constants) are no longer defined.
Pica interrupt masks are now constant expressions instead of constant
values.
TODO:
* factor out the common #defines into src/sys/arch/mips.
* Get rid of the Sprite coding-style names (MACH_xxx).
* Separate out the r3k/r4k differences from the Pica/pmax differences.
* Figure out how to have a run-time choice of r3k vs. r4k support,
instead of a compile-time choice.
to mips/include/asm.h.
Until all references to <machine/machAsmDefs.h> in the pmax and
pica tree are changed to use <mips/asm.h> directly, just do
#include <mips/asm.h>, for compatibility.
opcodes from the Pica port. Per Fogelstrom claims the latter are all
supposedly MIPS-II (r6000) instructions, rather than MIPS-III (R4000),
but we haven't checked to be sure. Are LL/SC really in MIPS-II?

versions work correctly; at some point between then and the immediately
preceding revisions, the "stylistic" changes to one (or both) stdarg.h
and varargs.h broke passing doubles to printf().
