Fwd: svn commit: r261871 - head/sys/mips/conf

[Adrian Chadd]

sorry for the cross-posting.

So, the basic wifi bits are now probing, attaching and (for some
values of work) working. There's still stuck beacons at interface up
time that I need to diagnose in case I really am gating the beacon
queue incorrectly.

But, boards like the D-Link DIR-825 rev C1 which have an AR9344 and an
external AR9380 should now work.

I'll sort out USB tomorrow, then I'll move onto the external switch
support and audio support.

Please let me know if you have further success with any AR9344 boards.
There's a lot of cheap AR934x stuff out there now which has 128MByte
or more RAM. (I think the SoC supports up to 256MByte of physical
RAM.)

New Revision: 261871
URL: http://svnweb.freebsd.org/changeset/base/261871

Log:
  Enable use of the PCIe connected wifi on the DB120 (AR9344) board.

  The on-board NIC is an 3x3 AR9380 with 5GHz only.

  * enable pci code in AR9344_BASE
  * enable ath_pci and the firmware loading bits in DB120
  * add in the relevant hints in DB120.hints to inform the probe/attach
    code where the PCIe fixup data is for the onboard chip.

  This is only relevant for a default development board.  I also have a
  DB120 with the on-board PCIe wifi NIC disabled and it's exposed as
  a real PCIe slot (to put normal PCIe NICs in); the fixup code will need
  to be disabled to make this work correctly.

  Tested:

  * DB120
