This option cannot support BCM2836/BCM2837-based Raspberry Pis such as the RPi 2 and RPi 3 due to different peripheral address maps. This option creates a build targetting the ARM1176 ISA. select BCM2835 select CPU_ARM1176 config TARGET_RPI_2 bool "Raspberry Pi 2" help Support for all BCM2836-based Raspberry Pi variants, such as the RPi 2 model B. This option also supports BCM2837-based variants such as the RPi 3 Model B, when run in 32-bit mode, provided you have configured the VideoCore firmware to select the PL011 UART for the console by: a) config.txt should contain dtoverlay=pi3-miniuart-bt. b) You should run the following to tell the VC FW to process DT when booting, and copy u-boot.bin.img (rather than u-boot.bin) to the SD card as the kernel image: path/to/kernel/scripts/mkknlimg --dtok u-boot.bin u-boot.bin.img This works as of firmware.git commit 046effa13ebc "firmware: arm_loader: emmc clock depends on core clock See: https://github.com/raspberrypi/firmware/issues/572".

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.
