I came across libubootenv the other day. Whatever solution you come up
with to manage the variables could use this library. It's in
tools/env/ in the u-boot sources.

I would caution against the u-boot environment being used as a general
purpose settings store. We should use it for configuring u-boot, and
keep other settings somewhere else in the system.
