Then again, U-Boot environment structure is trivial, crc, flags, data,
there is no complexity involved. There is probably some complexity in
the backing store access stuff (MTD, block devs, legacy stuff), but that
should either use some MTD utils libs, basic block access primitives or
be given a once-over and possibly be dropped.

I think prototyping a library from scratch that's LGPL would be a few
days' work and the benefit would be tremendous all over.
