Good point. On my board it's 0xffffffff, set even before U-boot starts, and lots board support code in U-boot expects this. I can't immediately find examples in the linux source code that actually writes to the scfg, so I don't know if we already have that as an implicit assumption as well. But it would be kind of nasty to have to make the code read SCFG_SCFGREVCR and decide the bit pattern to use based on that - especially since I wouldn't be able to test it.
Who thought such a magic switch could ever be a good idea?
