Intel SoC IOSF Sideband support for SoC platforms

modulename: iosf_mbi.ko

configname: CONFIG_IOSF_MBI

Linux Kernel Configuration
└─>Processor type and features
└─>Intel SoC IOSF Sideband support for SoC platforms
In linux kernel since version 3.10 (release Date: 2013-06-30)  
This option enables sideband register access support for Intel SoC
platforms. On these platforms the IOSF sideband is used in lieu of
MSR's for some register accesses, mostly but not limited to thermal
and power. Drivers may query the availability of this device to
determine if they need the sideband in order to work on these
platforms. The sideband is available on the following SoC products.
This list is not meant to be exclusive.
- BayTrail
- Braswell
- Quark

You should say Y if you are running a kernel on one of these SoC's.
