Don't put the MVME1xx model defines into IDENT, make them defflag options and
put them in opt_mvmeconf.h. Make these options depend on the appropriate
M680x0 option (MVME147 -> M68030, MVME16[27] -> M68040, MVME17[27] -> M68060)
so that the CPU option appears correctly in opt_m68k_arch.h.

- Determine KERN_AS automatically depending on whether OPT_MODULAR is
set or not, in the same way as libcompat.

- Specify OPT_MODULAR in the port Makefile instead of KERN_AS.

Now, KERN_AS=library is used for kernels without module(7) for all ports.

OK christos

branches: 1.67.2;
fix various gcc6 m68k issues:
- bad indentation. next68k en.c and mvme68k le_poll.c fixes real issues
in error handling, the rest are NFCI.
- pass 68030 flags as appropriate for mvme68k.
- next68k nextrom.c has -Warray-bounds ignored for an odd expression
that appears to run before relocation, and needs manual offsets
added which trips bounds array checking.

with this all m68k ports build with GCC 6.

branches: 1.66.16;
Declare dependency on fpsp.o via newly introduced ${MD_LIBS} instead of
${MD_OBJS}.

${MD_OBJS} should be used only for objects that must be linked first (i.e.,
start code). Objects have to be compiled following common compile rules,
and have to be generated into common places (i.e., top of kernel build
directory).

${MD_LIBS} defines libraries that are built by separate makefiles, under
separate directories. `Makefile.kern.inc' doesn't know intermediate library
objects.

branches: 1.65.6;
Specify both -Wa,-march=68030 and -Wa,-mcpu=68030 in -m68060 case for gcc45.

Now VME177 builds with both gcc45 and gcc48
(though untested on the real machines).

XXX: is it really worth to use -m68060 (instead of -m68020-60)
for kernel binaries?

Fix "Error: unrecognized option -mcpu68030".

fixes for gcc-4.8 (John D. Baker)

branches: 1.62.4; 1.62.14; 1.62.18;
Switch remaining platforms to modern CPP for assembler.

branches: 1.61.32; 1.61.38; 1.61.40;
Add assym.h dependencies.

branches: 1.60.50; 1.60.56;

s/GENASSYM/GENASSYM_CONF/ so we can use "GENASSYM" as the program name.

Add the %MAKEOPTIONSAPPEND token at the end of the file, after the
common Makefile.kern.inc has been included.

branches: 1.57.6; 1.57.10;
The traditional C preprocessor is fixed in GCC 3.3 now, so no need
to skip -traditional-cpp for HAVE_GCC3.

Don't use -traditional-cpp if HAVE_GCC3.

branches: 1.55.8;
Roll the rest of the ports over to the new MI kernel build machinery.
Any problems reported by testers have been fixed, and massive
cross-compiling of kernels has shown that any problems that remain
with actually building kernels are not related to this.

cleanup:
options SPACE TAB
makeoptions TAB
psuedo-device TAB
remove trailing whitespace
replace multiple spaces -> tabs
options "FOO" -> options FOO
options "FOO=bar" -> options FOO=bar
options "FOO=\"bar\"" -> options FOO="\"bar\""

branches: 1.53.2;
Change defaults for kernel compiles. Default all to USETOOLS?=no and have
the etc Makefile override that by putting USETOOLS into $.MAKEOVERRIDES
This way the default for kernel compiles is still to use the installed
toolchain instead of depending on $TOOLDIR. $TOOLDIR can be used by
simply adding USETOOLS=yes to the command line as usual.

Adjust each ports template to set the default no setting and also pull in
bsd.own.mk if they weren't already to ensure they'll build correctly
with the new toolchain setup.

branches: 1.52.2;
Set MACHINE_ARCH explicitly in Makefiles for which it is constant.
Also, since config(8) now explcitly sets MACHINE, there is no need
to do it here in the Makefile.

branches: 1.51.2;
define _KERNEL_OPT as well as _KERNEL. we will use this in the future to
get kernel "opt_foo.h" headers, rather than _KERNEL && !_LKM.

branches: 1.50.2;
delete obsolete comment

Add support for the m68060-based machines: MVME-172 and MVME-177.
CPU support taken from a combination of NetBSD/amiga and NetBSD/x68k.

At this time, MVME-172 works but MVME-177 is untested. Since the '177
is otherwise identical to the MVME-167, this should *just work*.

Add "install" target, so "make install" after building the kernel
does something useful. The target can be redefined by putting a
install-kernel-${MACHINE_NAME} target that fits your needs into
/etc/mk.conf.

HAVE_GCC28 -> HAVE_EGCS, and make it match gcc 2.9 as well. Also,
make the use of -Wno-uninitialized explicit, don't rely on a compiler
hack to do it for us.

Merge 'scw_mvme68k_bus_space' branch with the trunk.
These changes add support for:

o The MI VMEbus framework on both MVME147 and MVME167.
o Enhancements to the existing MD bus_space(9) implementation.
o Most of the bus_dma(9) API.

branches: 1.45.2;
Revert STRIPPROG -> STRIP

Add "dependall" target for comfort.

STRIP -> STRIPPROG

Change STRIPFLAGS=-g for cross-toolchains.

branches: 1.41.2;
be more efficient when doing the SYSTEM_LD_TAIL for -g kernels: don't
copy them just to strip them, use strip -o.

clean up a bit after jason :)

- fix emitrules() like emitfiles() to deal with the prefix (otherwise it
would attempt to find the file in the normal base for the NORMAL_C rule).
- add emitincludes() which adds include directives for each prefix to the
$INCLUDES variable in the makefile.
- add %INCLUDES to each Makefile.arch to deal with the above.

this makes "prefix" actually work in a usable manner, and now i can move
on to fixing compiler warnings (errors) in the ESP code. :)

branches: 1.39.6;
Some minor, mostly costmetic, changes to CPPFLAGS/CFLAGS.

Don't define "mc68020". Nothing uses it.

Add -Wpointer-arith warning since `void *' arithmetic is not ANSI C.

change handling of libkern:
-sys/lib/libkern builds as library per default (as it was documented all
the time)
-ports able to LKM set "KERN_AS=obj" explicitely in their Makefiles
(for now; should depend on actual "option LKM" or -better- functions
included for LKM use should be pulled in by a stub)
-always link libcompat before libkern - libkern stuff can be referred to
by libcompat, but not the other way

distclean is a synonym for cleandir

Specify a non-profiling C rule.

Add -Wno-main conditional on compiler being gcc 2.8 or egcs. (This adds
a HAVE_GCC28 check-variable that can now be used to add other gcc-2.8
flags in cases where they may be useful, or to remove gcc 2.7.2 "bug
workaround" flags.)

Make sure CPP, AR, AS, and RANLIB are defined.

Define LORDER, NM, and TSORT here, like we do the rest of the tools.

branches: 1.30.2;
define SIZE?=size, and use ${SIZE} instead of size. makes cross
compilation easier

PR/4162: Chris Jones: make cleandir does not work properly; it does not
remove the object files and the .depend file in the kernel build directory.

FPCOPROC is no longer used here.

Kill vestiges of Locore.c.

branches: 1.26.2;
Generate assym.h dependencies when making 'depend'.

Sync with hp300.

Zap AFLAGS

Support cross-compilation.

Put the genassym.sh output in a temp file, and mv -f it, in case
it fails spectacularly and doesn't clean up. Also, remove dependencies for
genassym.o (since it no longer exists).

Use genassym.cf, to support cross-compiling.

remove "::" entries as per cgd

Nuke some options GENERIC residue.

Nuke some GENERIC residue.

* Replace explicit -O2 in CFLAGS with COPTS macro. Default COPTS?= -O2.
Lets users over-ride with makeoptions COPTS="..." in kernel config files.

Leave `mandatory' flags (like -msoft-float which on m68k enforces no
FP in kernel) in CFLAGS.

Move strip(1) flags into a separate variable, so that $STRIP can
be passed to subordinate make(1)s. Remove $TOUCH. Add HOSTED_CC,
HOSTED_CPPFLAGS, and HOSTED_CFLAGS, and use them when depending genassym.

Wrap the default definition of `S' in `.ifndef'.

Put into . Remove hooks for `config-dependent' and
`device-driver' flags.

* Add a HOSTED_C_C variable, which strips `-p', `-pg', and
`-nostdinc', and use it when building genassym.
* Use `-nostdinc' just to be sure we're self-contained.

* Define CWARNFLAGS and MKDEP in some moderately consistent fashion.
* Make S expand to an absolute path at compile time.
* Use `-S' rather than `-x' to remove debugging symbols.
* Garbage collect unused variables.
* Reverse a handful of port-specific changes that do not correspond to
the common build model and are not needed.

Make `make depend' work for libraries.

Do not build vnode_if.[ch] for each kernel. Build them once, like the
various syscall sources/headers, and just compile them. From PR 2142, OK'd
by mycroft.

Define build programs with `?=', so they can be overridden with `makeoptions'.

Fix mkdep problems due to missing flags.

Use `-traditional-cpp' when building .s and .S files.

Clone these, and fix many bugs.

assym.s -> assym.h
(Some ports did this already.)

LOCORE -> _LOCORE

Compile the kernel with -Werror and -fno-builtin.
