Yeah. I tried to use the tools but they did not generate correct UBI
images. I tried to fix this and found out that the internals are too
messy to be maintainable, at least by me.

I cleaned-up what I could, made the utilities consistent, small, and
easy to maintain.

Vs. the PFI stuff, I also tried to clean-up this, but gave up after few
days, and just implemented another utility - ubinize.

I know what is PFI and I decided not to do this, because pfi =3D
configuration ini file + ubi images. I figured that it does not make
much sense to inroduce this additional magic format.
