Before anyone gets all trigger happy - there's significant work to be
done before the AR934x support is functional.

I'm committing this so the MIPS people can help me add/fix the mips74k support.

I'll give people a heads-up once I have the basics up and going (ie
CPU, ethernet, USB, flash, wifi, switch phy.)

New Revision: 253512
URL: http://svnweb.freebsd.org/changeset/base/253512

Log:
  Add some initial board support for the AR934x and the Qualcomm Atheros
  DB120 development board.

  The AR934x SoCs are a MIPS74k based system with increased RAM addressing
  space, some scratch-pad RAM, an improved gige switch PHY and 2x2 or 3x3
  on-board dual-band wifi.

  This support isn't complete by any stretch; it's just enough to bring
  the board up for others to tinker with.  Notably, the MIPS74k support
  is broken.  However it boots enough to echo some basic probe/attach
  messages, before dying somewhere in the TLB code.

  Thankyou to Qualcomm Atheros for their continued support of me doing
  open source work with their hardware.

  Tested:

  * AR9344, mips74k

Added:
  head/sys/mips/conf/AR934X_BASE   (contents, props changed)
  head/sys/mips/conf/AR934X_BASE.hints   (contents, props changed)
  head/sys/mips/conf/DB120   (contents, props changed)
  head/sys/mips/conf/DB120.hints   (contents, props changed)

Added: head/sys/mips/conf/AR934X_BASE
