+Subject: x86/iosf: Add Kconfig prompt for IOSF_MBI selection
+
+From: "David E. Box" <david.e.box@linux.intel.com>
+
+commit aa8e4f22ab7773352ba3895597189b8097f2c307 upstream.
+
+Fixes an error in having the iosf build as 'default m'. On X86 SoC's the iosf
+sideband is the only way to access information for some registers, as opposed to
+through MSR's on other Intel architectures. While selecting IOSF_MBI is
+preferred, it does mean carrying extra code on non-SoC architectures. This
+exports the selection to the user, allowing those driver writers to compile out
+iosf code if it's not being built.
