+       Repurpose the SD card slot for getting access to the UART0 serial
+       console. Primarily useful only for low level u-boot debugging on
+       tablets, where normal UART0 is difficult to access and requires
+       device disassembly and/or soldering. As the SD card can't be used
+       at the same time, the system can be only booted in the FEL mode.
+       Only enable this if you really know what you are doing.
