It depends on which hardware interface you need between your CPU and the 
radio module.
You can have a look at :
- ConnectBlue
- RedPine
- Silex America
And many others.

I contacted ConnectBlue many years ago for a project using a PowerPC 
CPU. ConnectBlue delivered support only for little endian CPUs. It might 
have change since then.
At that time, I have chosen a RedPine module. I can't tell you if the 
module is ok. The project died before I work on this. I can only tell 
you that support is from India and this not easy to communicate with 
indian people.
I am currently working on a project using a Silex module (wifi + 
bluetooth). The module is interesting. I have not written the driver 
(the OS used is QNX Neutrino on this project). There is no driver for 
lwip. I am not sure one can get the information to write the driver.

From my experience, I'll recommend RedPine today. Simple to setup (SPI 
link), quite well documented, not too expensive.

Nicolas
