Like the v1, the work is really nice, but the dependency on vendor binary-only
tools doesn't make feel confident about merging this.
We have open source implementation for all boards, but still dependeing on
tools we must manually build isn't optimal.
What would be optimal would be to re-implement those tools into python
libraries and merge them into the u-boot tree then use them from binman.
But this could be merged as first step, them the python libaray could be
modified to support the binary tools & a probable python re-implementation.
