No Floating Point on SA1111.

The SA1111 has a Serial Audio Controller which can be attached to
a PCM D-to-A. There are drivers already written which you could
tweak for the D-to-A of your choice. Someone has already figured
out all the messy DMA and streaming stuff for you.
We are currently using the Cirrus Logic CS43L43 as a D-to-A with
the SA1111. The MP3's sound OK, but I'm no audio engineer.
The SA1111 has a few bugs with DMA. However, the 2.4 kernels
have managed to sort that out by defining a special DMA region
when the SA1111 is configured. There are a few platforms
out there that support the SA1111 - assabet is one.
