+ Support for all BCM2837-based Raspberry Pi variants, such as
+ the RPi 3 model B, in AArch32 (32-bit) mode.
+
+ This option assumes the VideoCore firmware is configured to use the
+ mini UART (rather than PL011) for the serial console. This is the
+ default on the RPi 3. To enable the UART console, the following non-
+ default option must be present in config.txt: enable_uart=1.
