OF_SEPARATE may indicate that the user wishes U-Boot to use a different device tree than one obtained via OF_PRIOR_STAGE. However, OF_SEPARATE may also indicate that the device tree which would be obtained via OF_PRIOR_STAGE is invalid, nonexistant, or otherwise unusable. In this latter case, enabling OF_BOARD_FIXUP will result in corruption of the device tree. To remedy this, only enable OF_BOARD_FIXUP if U-Boot is configured for S-Mode.
