50 | + Support for all ARM1176-/BCM2835-based Raspberry Pi variants, such as | |
51 | + the RPi Zero model W. | |
52 | + | |
53 | + This option assumes the VideoCore firmware is configured to use the | |
54 | + mini UART (rather than PL011) for the serial console. This is the | |
55 | + default on the RPi Zero W. To enable the UART console, the following | |
56 | + non-default option must be present in config.txt: enable_uart=1. | |
57 | + This is required for U-Boot to operate correctly, even if you only | |
58 | + care about the HDMI/usbkbd console. | |
