Well, the shortcoming is that it lets you specify impossible contraints. You get a warning from Kconfig when building such a configuration, but then it continues. > The problem with defconfig is also too many options I feel for a common case. > CONFIG_DMADEVICES=y > CONFIG_TI_EDMA=y > > Most if not all future OMAPs from will use EDMA.

No, I would still like you to not add it to either one. I'm spending a lot of my time tracking down incorrect 'select' statements and I'd rather spend it in a different way. I've had to a number of 'select' statements from OMAP in the past, please don't add any new ones unless there is a strict build dependency (which normally should not exist).
