hehe.. thanks also to the hard work committed in the ARM sub-tree in these
past (few!) months.

Yes, those two.

bcm4760 is the superset (bcm4761 hasn't the gpu) but there are also other
differences (that I know, USB phy and clocks).

I can identify the SoC at runtime, does this change anything to your
recommendation?

Thanks for the feedback.
