Introduction:
---------------
hwarc driver is for the radio controller of wireless USB HWA device. It attaches to the radio controller interface of a HWA device. It can be attached to the device by the following binding command:
# add_drv -i '"usbif,classe0.1"' hwa_rc

uwba module is the UWB Architecture module. It is for Ultra Wideband support on solaris. hwarc driver implements the interfaces defined in uwba module. The whci_rc driver component (planned in the future) will also implement the interfaces.
 
Current Code Status:
-----------------------
Both hwarc driver and uwba module are now in a prototype status. The whole architecture are done and the key functions are implemented. They are tested and verified that the code architecture and the functions are working in the expected way. No heavy tests are performed.

Todo list:
----------
- Polish the lock deployments
- Polish the power management part
- Cstyle
