Hi Mark,

Overall, I think this approach looks good.  A minor comment below.

Also, this will require some slight rework on the clock front after I
merge the clkdev patch.

This current approach will not quite work for current modules that use
cpu_is_* because the davinci_soc_info symbol is not exported to
modules.  This causes it not to build for DaVinci git but it actually
exposes a problem that needs to be fixed.  In general, drivers
shouldn't be using cpu_is_* in the first place.  Ideally, they should
be using platform_data for this.

This currently only affects MMC and MUSB. 

I'll submit a patch to fixup MMC by adding more platform_data options.
That only leaves MUSB to cleanup.

I agree with Dave on this one.   Just use standard struct decls here.

You should probably drop the __initdata too and then you don't need to
alloc bootmem and copy the initdata.  I don't see the gain in using
initdata if it just copied to bootmem later.
