+ 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.
