I designed these modules into a product about a year ago. Our system uses a
Samsung S3C2443 ARM920T CPU and we're running a commercial OS (smx).

At the time, ZeroG was able to provide us with Microchip specific drivers
(which we didn't use) and a generic driver development package. They also
had a driver package for Linux which they used to benchmark the modules
under Linux with an ARM9 CPU (much like our system). We ultimately ported
the generic drivers to the smx OS. They told us the Linux drivers had some
rough edges and weren't production ready but they sent them to us anyway.
My software engineer had a small linux system up and running on our
hardware in a few days for our own benchmarking so I know they couldn't
have been too bad.

We have much more detailed data than is publicly available but we had to
sign an NDA to get them.

I'm not sure what the situation is now that Microchip owns them but I think
the information and drivers you want probably still exists.

I would get in touch with the product manager at Microchip for the ZeroG
modules. They should be able to tell you for sure.
