AC97 sound support in uClinux

We are developing a custom board which shall run uClinux and 

provide audio I/O. So I am investigating which audio chips are 

natively supported by the NIOS port of uClinux to prevent driver  

development.  

 

I thought about the AC 97 core from opencores or an  

Anlalog Devices audio codec. 

 

Do you have any experience or can give me a few hints? 

 

thanks, 

Klaus

You may look at linux-2.6.x/sound/arm/pxa2xx-ac97.c . 

And this link may help,
