I have no idea how common this is but Fedora does enable this option.
If you are interested in salvaging this, please speak up!


Grepping config and the kernel it seems Moorestown is the Intel MID
platform and we explicitly disable X86_INTEL_MID so I'm not sure it's
a problem.


Yeah I'm pretty sure this is just for the Intel X86 "phone" SoCs which
never went anywhere. As you know I've spend a lot of (spare) time on
improving support for Intel Atom based hw (mainly Bay Trail and Cherry
Trail tablets) and even I don't care for the phone chips, for one exactly
because of SFI, instead of coming with EFI these phones come with some
frankenstein firmware AFAIK, I never even bothered getting one to try
and make it boot mainline ...

TL;DR: I do not think this will missed, actually I think it should be
fine to disable it in the Fedora kernels right away. I've just disabled
it for the builds which I do from my personal kernel tree. It does not
seem to affect any other Kconfig options.

Regards,

Hans



Ah the x86 phone. Such dreams. Thanks for the confirmation Peter and Hans.
I'm planning on dropping a bunch of stuff after 5.3 releases so I'll turn it
off in rawhide there.
