Support for all ARM1176-/BCM2835-based Raspberry Pi variants, such as
the A, A+, B, B+, Compute Module, and Zero. 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.

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 creates a build targetting the ARMv7/AArch32 ISA.
