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.
