Expanding RAM at runtime startup

I have a platform that can be build with 32 or 64Meg of RAM.

I would like to build just one image that will support them both (i.e.
available ram determined at run time).

I seem to recall there may be an API call that could do this.
Basically I would build the image for 32M and upon startup it would sense if
64M is available and if so expand available RAM.

I think the call was made in OALInit function.

Does anyone know the call and were and how to use it?

You should implement OEMGetExtensionDRAM inside your OAL.

And note that *you* are responsible for determining if there really is
additional RAM available. You implement one of these calls, and use it to
tell the OS how much RAM there is. The function doesn't figure it out on
it's own.
