I think that would take two passes to do currently for the depenencies.. But we can certainly select all the omap drivers as modules in omap2plus_defconfig. > In order to get to a minimal kernel, in theory, we don't need regulator, > i2c, MFD, or twl4030* built in.

I think the only thing keeping us from doing that is that most of the boards don't use initramfs. Without initramfs these are needed to mount root on MMC. > If someone is looking for a good omap-kernel-janitors project, I would > suggest getting to a *really* minimal OMAP2+ kernel with everything > possible built as modules to be a very good project. Agreed. The way to do that is to set everything possible as modules in omap2plus_defconfig, and move to kernel + initramfs based booting like most distros do.
