No better time then the present... Add/edit as you see fit.  Then we can at
least assign some tasks out

Goal for document:  Allow an experienced engineering team to port existing
hardware to OpenBMC
Topics:
- Yocto Layering to support your board
- Does your hardware have supported device drivers
- How to deal with non hwmon supported devices
- How to implement the default set of packages (thermal, inventory, ipmi,
led, etc)
- How to swapping a default package with a proprietary one
- Adding packages
- Testing against the OpenBMC verification suite
