Hi Arnd

CPU_FEROCEAN is currently selected by Orion5x, Kirkwood and mv78xx0.
These are all ARMv5 machines. As far as i understand, we cannot
combine ARMv5 with ARMv6 and above. So is this really an issue? Should
we put in something defensive to prevent it being selected on anything
other than ARMv5?
