Use the opt_ah.h for the provided HAL to get options like AH_REGOPS_FUNC.
Add AH_REGOPS_FUNC to a few opt_ah.h that don't have it in this version
of the HAL but need it. (The next version from Sam should have this fixed
in it. If it doesn't, then we'll have to take care at import time.)
Ultimately, this should make future imports even easier, and individual ports
should not have to worry about whether AH_REGOPS_FUNC is properly defined or
not, since the opt_ah.h will just take care of it automatically.
Ok'd by dyoung@.
can automatically use the AH_XXX options that the HAL was built, without
requiring additional machine-specific configuration.
A follow up commit will activate this change.
the rules due to needing to conditionally postprocess the HAL object file.
Macppc needs a a non-ELF HAL (EABI) object, so take care of that by default
in the atheros include file.
including easy override mechanism for ports that need it.
To use this, just .include this file instead of listing explicit rules
for building the target. A change to std/conf/files will be made shortly
that lists /athhal.o as an object if "ath" is defined.
If you need to override the default HAL selected for some reason (for example
to use an xscale version of the HAL on evbarm kernels that support it), add
a "makeoptions ATH_MACHINE_HAL=<hal>", for example to select the XScale
LE configuration you could use "makeoptions ATH_MACHINE_HAL=xscale-le-elf".

The new layout almost precisely matches FreeBSD, and should make
future imports much easier.
At the same time, import the current 0.9.16.16 HAL from FreeBSD. According
to sam@, this is the proper version we should be using.
