I don't think this is a good idea. This logic does not belong into U-Boot; if anywhere, it belongs into the Linux kernel code. If I want to pass any specific value to the Linux kernel I want that U-Boot does not get in my way. And if I decide to set the mpurate to "auto" I want that U-Boot keeps this setting and does not change it silently behind my back into something else. Both looks conceptually broken to me.

The other was that they were made of ice. -Terry Pratchett, _Sourcery_
