yosemite v4 bmc emulation.\n\nThe goal of this machine support is to support OpenBMC development.\n\nReference linux devicetree from openbmc linux is [2].\n\nStatus:\n- Enclosure FRU: showing up\n- Management Board FRU: showing up\n- Blade Board FRU: showing up\n- Blade Board sensors: not implemented\n- Blade Chassis FRU: showing up\n- Fan Board FRU: both showing up\n- Fan Board sensors: supported\n\nOverall the emulation is incomplete but already helpful in development\nand testing.\n\nThe focus of this initial support is on the FRU eeproms and fanboard\nsensors.\n\nTested: booted an OpenBMC image for yosemite4 target.\n\nReferences:\n[1] https://github.com/9elements/qemu/commit/32139f913c2bd0ebe4bd26c46765861f6f9f2d49\n[2]
