freebsd-dev/sys/modules/Makefile
Adrian Chadd 41059135ce [ath] [ath_hal] (etc, etc) - begin the task of re-modularising the HAL. 
In the deep past, when this code compiled as a binary module, ath_hal
built as a module.  This allowed custom, smaller HAL modules to be built.
This was especially beneficial for small embedded platforms where you
didn't require /everything/ just to run.

However, sometime around the HAL opening fanfare, the HAL landed here
as one big driver+HAL thing, and a lot of the (dirty) infrastructure
(ie, #ifdef AH_SUPPORT_XXX) to build specific subsets of the HAL went away.
This was retained in sys/conf/files as "ath_hal_XXX" but it wasn't
really floated up to the modules themselves.

I'm now in a position where for the reaaaaaly embedded boards (both the
really old and the last couple generation of QCA MIPS boards) having a
cut down HAL module and driver loaded at runtime is /actually/ beneficial.

This reduces the kernel size down by quite a bit.  The MIPS modules look
like this:

adrian@gertrude:~/work/freebsd/head-embedded/src % ls -l ../root/mips_ap/boot/kernel.CARAMBOLA2/ath*ko
-r-xr-xr-x  1 adrian  adrian    5076 May 23 23:45 ../root/mips_ap/boot/kernel.CARAMBOLA2/ath_dfs.ko
-r-xr-xr-x  1 adrian  adrian  100588 May 23 23:45 ../root/mips_ap/boot/kernel.CARAMBOLA2/ath_hal.ko
-r-xr-xr-x  1 adrian  adrian  627324 May 23 23:45 ../root/mips_ap/boot/kernel.CARAMBOLA2/ath_hal_ar9300.ko
-r-xr-xr-x  1 adrian  adrian  314588 May 23 23:45 ../root/mips_ap/boot/kernel.CARAMBOLA2/ath_main.ko
-r-xr-xr-x  1 adrian  adrian   23472 May 23 23:45 ../root/mips_ap/boot/kernel.CARAMBOLA2/ath_rate.ko

And the x86 versions, like this:

root@gertrude:/home/adrian # ls -l /boot/kernel/ath*ko
-r-xr-xr-x  1 root  wheel   36632 May 24 18:32 /boot/kernel/ath_dfs.ko
-r-xr-xr-x  1 root  wheel  134440 May 24 18:32 /boot/kernel/ath_hal.ko
-r-xr-xr-x  1 root  wheel   82320 May 24 18:32 /boot/kernel/ath_hal_ar5210.ko
-r-xr-xr-x  1 root  wheel  104976 May 24 18:32 /boot/kernel/ath_hal_ar5211.ko
-r-xr-xr-x  1 root  wheel  236144 May 24 18:32 /boot/kernel/ath_hal_ar5212.ko
-r-xr-xr-x  1 root  wheel  336104 May 24 18:32 /boot/kernel/ath_hal_ar5416.ko
-r-xr-xr-x  1 root  wheel  598336 May 24 18:32 /boot/kernel/ath_hal_ar9300.ko
-r-xr-xr-x  1 root  wheel  406144 May 24 18:32 /boot/kernel/ath_main.ko
-r-xr-xr-x  1 root  wheel   55352 May 24 18:32 /boot/kernel/ath_rate.ko

.. so you can see, not building the whole HAL can save quite a bit.
For example, if you don't need AR9300 support, you can actually avoid
wasting half a megabyte of RAM.  On embedded routers this is quite a
big deal.

The AR9300 HAL can be later further shrunk because, hilariously,
it indeed supports AH_SUPPORT_<xxx> for optionally adding chipset support.
(I'll chase that down later as it's quite a big savings if you're only
building for a single embedded target.)

So:

* Create a very hackish way to load/unload HAL modules
* Create module metadata for each HAL subtype - ah_osdep_arXXXX.c
* Create module metadata for ath_rate and ath_dfs (bluetooth is
  currently just built as part of it)
* .. yes, this means we could actually build multiple rate control
  modules and pick one at load time, but I'd rather just glue this
  into net80211's rate control code.  Oh well, baby steps.
* Main driver is now "ath_main"
* Create an "if_ath" module that does what the ye olde one did -
  load PCI glue, main driver, HAL and all child modules.
  In this way, if you have "if_ath_load=YES" in /boot/modules.conf
  it will load everything the old way and stuff should still work.
* For module autoloading purposes, I actually /did/ fix up
  the name of the modules in if_ath_pci and if_ath_ahb.

If you want to selectively load things (eg on ye cheape ARM/MIPS platforms
where RAM is at a premium) you should:

* load ath_hal
* load the chip modules in question
* load ath_rate, ath_dfs
* load ath_main
* load if_ath_pci and/or if_ath_ahb depending upon your particular
  bus bind type - this is where probe/attach is done.

TODO:

* AR5312 module and associated pieces - yes, we have the SoC side support
  now so the wifi support would be good to "round things out";
* Just nuke AH_SUPPORT_AR5416 for now and always bloat the packet
  structures; this'll simplify other things.
* Should add a simple refcnt thing to the HAL RF/chip modules so you
  can't unload them whilst you're using them.
* Manpage updates, UPDATING if appropriate, etc.
