Initial patch based on [1] to support yosemite v4 bmc emulation. The goal of this machine support is to support OpenBMC development.
Reference linux devicetree from openbmc linux is [2]. Status: - Enclosure FRU: showing up - Management Board FRU: showing up - Blade Board FRU: showing up - Blade Board sensors: not implemented - Blade Chassis FRU: showing up - Fan Board FRU: both showing up - Fan Board sensors: supported Overall the emulation is incomplete but already helpful in development and testing. The focus of this initial support is on the FRU eeproms and fanboard sensors. Tested: booted an OpenBMC image for yosemite4 target.
