The i.MX6/i.MX7 is capable of booting a secondary "redundant" system image in case the primary one is corrupted. The user can force this boot mode as well by explicitly setting SRC GPR10 bit 30. This can be potentially useful when upgrading the bootloader itself. Expose this functionality to the user.
