I tested you're patch and can confirm it works. Can I do anything to get
this
patch accepted into GIT?
I also quickly looked into you're review comment about BAYTRAIL_SMM. It
is only
used in src/soc/intel/fsp_baytrail/acpi.c. The only thing I can say
about this
is that if I force this ifdef to true and add 'cpu/x86/smm.h' to the
includes,
I can still build a booting firmware and boot Linux. But since I don't
know
what this code does, I can't say if this is the correct solution.
Kind regards,
David
