If the old command-line is ever going to be removed, there's no point supporting both at all; I'd have to hack my scripts to support both sometime, so I may as well do it now rather than wait. >> Otherwise, I guess I'll have to hack my scripts to check whether e.g. scripts/multiconfig.py (which was added in this commit) is present in the tree, and execute different build commands based on that... > > > Do you mean, you need to build some different versions of U-boot ? Yes. I own some scripts that build U-Boot, and they need to work on any reasonable version of U-Boot that anyone might want to build. For example, they build 2014.07 just fine, and there's no reason they should ever stop being able to do that. I obviously also want my scripts to be able to build any future version of U-Boot.
