As per hpa CE4100 platforms can also disable pnpbios [0]. Then Sebastian also recently noted that CE4100 also disables RTC probe, to do that Sebastian had long ago added the RTC of_have_populated_dt() check, he noted that it was meant to skip the RTC probe on all OF platforms but as of now, CE4100 was the only x86 DT using this. We can just fold this requirement into the platform quirk then. This now means that all of these match platform quirks for pnpbios and RTC preferences: * X86_SUBARCH_XEN * X86_SUBARCH_LGUEST * X86_SUBARCH_INTEL_MID * X86_SUBARCH_CE4100 [0] http://lkml.kernel.org/r/5702B5C2.7070101@xxxxxxxxx [1] http://lkml.kernel.org/r/570B52EA.60300@xxxxxxxxxxxxx Suggested-by: H.
