Shouldn't this be shared with the other AC97 devices?

I organized the code in 3 different drivers (PL041 <=> ACLink <=>
LM4549) to decorrelate the codec interface from its implementation. This
could allow the use of alternative AC97 models with the same PL041
implementation.
On the other hand the current ac97.c implementation is a closely coupled
combination of a PCI/ACLink bridge (Intel 82801AA) with a generic AC97
codec. This has prevent me to easily reuse this code.
The milkymist-ac97 implementation is another case. It looks like a basic
implementation with the AC97 registers directly mapped on the system bus.
Using the ACLink bus I defined, it could be interesting to implement
separately the PCI/ACLink bridge from ac97.c.
Is it what you mean by saying this should be shared with the other AC97
devices ?
