Currently no powerpc platform uses this driver for non-PCI devices and looking at commits history for powerpc dts files it seems that it also hasn't happened in the past. I think that the current patch is sufficient as we can always relax dependencies later if the need for it shows up + there is a possibility to (ab)use COMPILE_TEST for older kernels.

Moreover even if the new usage shows up it is not enough to enable driver for it to make it work as you also need to add a node describing your SATA MV variant to your SoC device tree file (which requires updating kernel source anyway).

You still have to recompile your kernel to update your device tree.. how... quaint ;-). It's not a generic limitation but I'm not that fussed. It seems a fair argument that there would be other changes made when this was being done for a system, and probably new board stuff. Alan
