The only use I can see is overriding a broken h/w value. We have this usecase in the Ux500. See these patches: http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=6829/1 http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=6830/1 Alas, it's not yet merged for the old boardfile world usecase, and causing us problems to drive our hardware already.
