Pull in Atheros HAL.

branches: 1.17.78; 1.17.86; 1.17.92;
merge ktrace-lwp.

include "conf/std".

branches: 1.15.16;
Remove historic remnant that treated the O2 load address as the
sgimips standard. Define it in the respective config file.

add "makeoptions MACHINE_ARCH=..." in std.* for mips ports
where it is constant (to ease cross-building).

branches: 1.13.6;
Remove the explicit `makeoptions MACHINE_ARCH="mipse{b,l}"' for kernel
builds and use the endianness of the toolchain being used to determine
the endianness of the kernel.

Change the kernel load address offset from 512K to 420K, the Irix
convention for debugging kernels.

Move the kernel forward in memory, starting it 512K in from the
bottom of RAM. The bootloader is now loaded 2K in from the bottom
of RAM, so we need to make space for it.

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\""

Remove driver options that don't belong in std.sgimips.

branches: 1.8.4;
For MIPS kernel Makefiles, don't set ENDIAN in std.${MACHINE}. Instead,
explicitly set MACHINE_ARCH to the appropriate thing. Makefile.mips will
then set all of the internal variables it needs to accordingly.

branches: 1.7.2;
Delete __NO_SOFT_SERIAL_INTERRUPT.

branches: 1.6.2;
Revert back to a machinearch (really cputype) of mips. Put ENDIAN back.

Change arch from mips to mipsel/mipseb as appropriate. Nuke the ENDIAN
makeoption. Key off MACHINE_ARCH for adding -EB/-EL to CFLAGS/AFLAGS/LD/
LINKFLAGS.

Start using a Makefile.mips. Use a combination of makeoptions and
Makefile.sgimips.inc which has sgimips specific stuff.

branches: 1.3.2;
Update for counter interrupt PSL change.

Remove prefix construction for softdeps. Add SOFTDEP option to GENERIC.

branches: 1.1.2; 1.1.4;
Initial commit.
