Add prototyped declarations for scsiGroup0Cmd and scsiGroup1Cmd.
Add prototype declarations for scsiPrintSense. Cut the inqiury-response
pretty-printer from tz.c and rz.c and paste it in as scsiPrintInquiry.
-Wall -Wmissing-prototypes:
Add prototypes.
Fix printf() format strings (%x vs pointer-arg, %x with a long int).
Fix a possibly-uninitialized shadowing local variable "resid" in tzdone().
include <sys/systm.h> to get prototypes for printf() and bcopy().
Move to mips/pmax/genassym.c, as (most of) the assembler locore code is
being merged into a generic-MIPS locore.
Remove the redundant pmax/pmax/genassym.c.
* cut-and-paste all the code for both r2000 (MIPS-I) and r4000 (MIPS-III)
into both the pica and pmax locore.S.
* Change the names of the small segments of vector code that are
bcopied to the machine vector locations, to avoid clashing.
Get rid of the Sprite MachXXX names for the vector code, and
use use mips_r2000_xxx and mips_r4000_xxx instead.
Update the names used in the vector-copying code and trap handlers
to match.
* Most of the rest of the pica locore.S was copied from the pmax
locore.S, and then edited to work on an r4000. The names of
functions and of manifest constants stayed the same, although
both assmbler code and constant values changed.
cut-and-paste such code into contiguous blocks protected by
#if / #endif. Much of the cache and trap-handling code
needs r3000-only register fields, on the r3000, and r4000-only
insns and registers on the r4000.
* change the pmax r2000 exception-handling code to extract a trap
code with the user/kernel bit at 0x20 rather than 0x10.
(r2000s have 4-bit execption codes, r4000s have 5-bit.)
Use the a 16 from-user-space + 16-from-kernel space jump table,
just like on the r4000 pica port.
* add NOPs to the common code where required by the r4000 pipeline
constraints.
* add _C_LABEL() macros to the r4000 locore.
Comitted to provide a snapshot for others to test, and work on a cleaner merge.
* 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.

A merged version with the NetBSD/pmax revision history is in mips/mips/.

* Delete pmax-specific functions and declarations from trap.c
* Delete mips-geeneric functions and declaratinos from pmax_trap.c
* Rename the function pointer used to handle hardware interrupts to
"mips_hardware_intr". Define it in trap.c. Change references elsewhere,
including machdep.c.
Verified to boot on a 5000/200.
* Add spl4() and spl5() functions from the Pica port.
* Add MachFPTrap() as an alternate entry point for MachFPInterrupt.
The r4k reports floating-point execptions as a trap, not an interrupt,
and the Pica port uses the name MachFPTrap().
* Add nops to the Mach_spl?() functions and MachFPInterrupt, as required
for the r4k port.
Commit "floppy" interrupt counter for vmstat -i.

Copy the kn02 memory-interrupt reporting function to the kn03 (5k/240)
memory-error handler, since the 3MAXPLUS seems to use the same ECC hardware
as the 3MAX.

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?

code following the MIPS ELF abi.
* Move the kn01 interrupt handler outside of #ifdef DS5000, to support
3100-only kernels.
* Add #ifdef DS3100 around kn01_enable_intr() to allow configuring
turbochannel-only kernels.
Configuration-time support for specific models of DECstation still needs
more thought/work.

the NetBSD-1.1 convention. Change the mainbus `struct confargs'
and the "generic" interrupt-establish method, used by devices that
appear on both a kn01 and TC decstations, to match.
Change the macros in autconf.h accordingly.
Add new device-attach struct cfattach le_tc_ca and struct cfdriver le_cd.
Change IOASIC cfdriver references from "ioasiccd" to "ioasic_cd".
Change "mainbuscd" to "mainbus_cd"
update the old-config to new-config glue used with the 4.4bsd/pmax
SCSI drivers to use new device attach declarations and names for
the "oldscsibus", "tz" and "rz" drivers.
- split softc size and match/attach out from cfdriver into
a new struct cfattach.
- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.
