This is nice and somehow cool to be able to just disassemble some code
under barebox. However, it's quite a bunch of code imported from another
project and we'll need even more code for other architectures. This code
needs maintenance to stay useful, so I am not very fond of merging it.
What is your usecase for this? Normally I would transfer the area I'd
like to disassemble via tftp or whatever to a host and disassemble it
there, but that it something that I need very seldomly.
