Well, my comment on start op was regarding your observation of CHIPCTL
being zero. As the start op does reinitialize the hardware you should
check CHIPCTL register at the end of it. This is just to confirm the
register contains valid bits.

So I agree with Hauke and have this code in bcma. Just not sure whether
bcma_pmu_workarounds() is the place to put it. This is not a pmu related
register, but as the function was already there I will not stress to
move it to driver_chipcommon.c ;-)
