+ Support for all ARM1176-/BCM2835-based Raspberry Pi variants, such as
+ the RPi Zero model W.
+
+ 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 Zero W. To enable the UART console, the following
+ non-default option must be present in config.txt: enable_uart=1.
+ This is required for U-Boot to operate correctly, even if you only
+ care about the HDMI/usbkbd console.
+
+ This option creates a build targetting the ARMv7/AArch32 ISA.
