You want to use the hciattach.  I have used this on one of my MCF5282 designs 
when talking to A7eng's bluetooth modules.

hciattach creates an hci device and brokers all requests over the UART to the 
bluetooth module.  From that point on you use everyday standard utilities to 
manipulate the hci device that was created.
