It would be best to see the "missing initialization" being added to board-generic/dts files.

The other board-*.c files will be dropped as soon as we have things usable with devicetree. And we're only two board-*.c files away from making omap4 device tree only ;) I think we are only missing DSS, USB and WLAN bindings to have blaze and panda usable with device tree to the point where everything else can be added later on.
