definitions.
* Include <mips/cpuregs.h> in <cpu.h> so kern_clock.c has user/kernel
status bits in scope. Still needs work; r2k/r4k previous-mode bits
are different.
* Include <mips/mips_param.h> in pica/include/param.h, for locore declarations,
and definitions of vm and other constants that should be shared across
NetBSD/mips systems to esnsure user-level binary compatibility.
* Add cast to hardclock when it's used directly as an interrupt handler.
* Add a null-interrupt-establish function, to avoid int vs void lint
in pica/dev/dma.c.
* fix include in pica/include/pccons.h to work with "standard"
kernel-compile include path.
* 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.
bus memory and I/O space access functions/macros, to be used by
machine-independent code for more sane access to bus resources.
New functions will be added to this set, in the future, as appropriate,
but this is a good starting set. Defines:
bus_{io,mem}_{map,unmap}
bus_{io,mem}_{read,write}_{1,2,4,8}
functions, and several types to go with them.
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.
