I guess I wasn't clear enough when I asked the series to be split.  I
want to see this portion turned into:
a) Move omap-common spl bits to arch/arm/lib/
b) davinci converted (and as needed, omap3/4/am33xx converted) to be
able to use the same code.

We shouldn't introduce a new spl_mmc.c for example, we should modify the
davinci structure to be able to re-use the same spl_mmc.c code to
load/verify and let the next step, as needed happen.  I want to see
"omap" be able to re-use SPI (since am33xx can do it too, and I've
kludged the davinci stuff before) and potentially be able to re-use for
example the gunzip support.  This I think is the easy set of steps to
being able to reuse this fairly common SPL logic outside of not just TI
parts but anyone else that wants it.
