But it breaks all SB600 boards with SPI flash.

I think that is the best we can do at this point.

It just makes me really sad and annoyed to require manual control
like that when the SB600 for all other flash chip purposes is totally
excellent - nice and simple! I just don't want to believe that noone
thought of mirroring the boot straps in some register.

..and quite likely instead require the use of -m for every SB600
