23 Support for all ARM1176-/BCM2835-based Raspberry Pi variants, such as
24 the A, A+, B, B+, Compute Module, and Zero. This option cannot
25 support BCM2836/BCM2837-based Raspberry Pis such as the RPi 2 and
26 RPi 3 due to different peripheral address maps.
27
28 This option creates a build targetting the ARM1176 ISA.

36 the RPi 2 model B.

38 This option also supports BCM2837-based variants such as the RPi 3
39 Model B, when run in 32-bit mode, provided you have configured the
40 VideoCore firmware to select the PL011 UART for the console by:
41 a) config.txt should contain dtoverlay=pi3-miniuart-bt.
42 b) You should run the following to tell the VC FW to process DT when
43 booting, and copy u-boot.bin.img (rather than u-boot.bin) to the SD
44 card as the kernel image:
45
46 path/to/kernel/scripts/mkknlimg --dtok u-boot.bin u-boot.bin.img
47
48 This works as of firmware.git commit 046effa13ebc "firmware:
49 arm_loader: emmc clock depends on core clock See:
50 https://github.com/raspberrypi/firmware/issues/572".

52 This option creates a build targetting the ARMv7/AArch32 ISA.

60 Support for all BCM2837-based Raspberry Pi variants, such as
61 the RPi 3 model B, in AArch32 (32-bit) mode.

63 This option assumes the VideoCore firmware is configured to use the
64 mini UART (rather than PL011) for the serial console. This is the
65 default on the RPi 3. To enable the UART console, the following non-
Stephen Warrenb2f48c22016-04-01 21:38:04 -0600[diff] [blame^]66 default option must be present in config.txt: enable_uart=1. This is
67 required for U-Boot to operate correctly, even if you only care
68 about the HDMI/usbkbd console.

88 At the time of writing, the VC FW requires a non-default option in
89 config.txt to request the ARM CPU boot in 64-bit mode:
90 arm_control=0x200
91
92 The VC FW typically provides ARM "stub" code to set up the CPU and
93 quiesce secondary SMP CPUs. This is not currently true in 64-bit
94 mode. In order to boot U-Boot before the VC FW is enhanced, please
95 see the commit description for the commit which added RPi3 support
96 for a workaround. Since the instructions are temporary, they are not
97 duplicated here. The VC FW enhancement is tracked in
98 https://github.com/raspberrypi/firmware/issues/579.
