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
