This is a first cut at the u-boot cli. It builds and loads and runs and has no commands. That's next. Interestingly, this is code right from our u-boot tree, and it's full of style violations which I don't intend to fix. Remove dependency on anything else, but this won't work until the libpayload serial drivers for arm are set up. BUG=None TEST=build and boot on nyan and get a u-boot cli prompt.
