My worry about using binman for cracking such a simple nut is the

I should probably update this. Unless you use compression and SPL symbols
you shouldn't need these.
Hi Simon. If it doesn't pull in these extra dependencies, please ignore my
concern/objection above. I was kind of hoping you'd tell me I was wrong! :)
We've just exorcised the pyelftools requirement for building Rockchip
u-boot; it would be a pity for to re-inflict it on users and casual
developers just for a convenience feature.
You mean make_fit_atf.py? Again I think that this logic should be moved
into binman. It doesn't actually have support to generic FITs but should.
We don't use a lot from this library so perhaps could adopt a similar
implmentation.
Happy to try to help if I can; ELF is just a collection of fixed C-style
structures so is dead easy to parse with Python's built in struct support.
The only (minor) complication for binman compared to make_fit_atf.py is the
need work across 32/64-bit and big/little-endian platforms. Field sizes and
therefore offsets vary between the two cases of 32-bit and 64-bit ELF
files. (I could just verify 64-bit little-endian ARM and then used fixed
offsets in make_fit_atf.py.)
Best wishes,
Chris.
