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_0_W

help
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.

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.

help
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. 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.
select BCM2837_32B
config TARGET_RPI_3
bool "Raspberry Pi 3 64-bit build"
help
Support for all BCM2837-based Raspberry Pi variants, such as
the RPi 3 model B, in AArch64 (64-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. This is
required for U-Boot to operate correctly, even if you only care
about the HDMI/usbkbd console.
At the time of writing, the VC FW requires a non-default option in
config.txt to request the ARM CPU boot in 64-bit mode:
arm_control=0x200
The VC FW typically provides ARM "stub" code to set up the CPU and
quiesce secondary SMP CPUs. This is not currently true in 64-bit
mode. In order to boot U-Boot before the VC FW is enhanced, please
see the commit description for the commit which added RPi3 support
for a workaround. Since the instructions are temporary, they are not
duplicated here. The VC FW enhancement is tracked in
https://github.com/raspberrypi/firmware/issues/579.
This option creates a build targetting the ARMv8/AArch64 ISA.
