39 Support for all ARM1176-/BCM2835-based Raspberry Pi variants, such as
40 the A, A+, B, B+, Compute Module, and Zero. This option cannot
41 support BCM2836/BCM2837-based Raspberry Pis such as the RPi 2 and
42 RPi 3 due to different peripheral address maps.
43
44 This option creates a build targetting the ARM1176 ISA.

53 This option also supports BCM2837-based variants such as the RPi 3
54 Model B, when run in 32-bit mode, provided you have configured the
55 VideoCore firmware to select the PL011 UART for the console by:
56 a) config.txt should contain dtoverlay=pi3-miniuart-bt.
57 b) You should run the following to tell the VC FW to process DT when
58 booting, and copy u-boot.bin.img (rather than u-boot.bin) to the SD
59 card as the kernel image:
60
61 path/to/kernel/scripts/mkknlimg --dtok u-boot.bin u-boot.bin.img

63 This works as of firmware.git commit 046effa13ebc "firmware:

73 Support for all BCM2837-based Raspberry Pi variants, such as

76 This option assumes the VideoCore firmware is configured to use the
77 mini UART (rather than PL011) for the serial console. This is the
78 default on the RPi 3. To enable the UART console, the following non-
Stephen Warren158c9c72016-04-01 21:38:04 -0600[diff] [blame]79 default option must be present in config.txt: enable_uart=1. This is
80 required for U-Boot to operate correctly, even if you only care
81 about the HDMI/usbkbd console.

99 At the time of writing, the VC FW requires a non-default option in
100 config.txt to request the ARM CPU boot in 64-bit mode:
101 arm_control=0x200
102
103 The VC FW typically provides ARM "stub" code to set up the CPU and
104 quiesce secondary SMP CPUs. This is not currently true in 64-bit
105 mode. In order to boot U-Boot before the VC FW is enhanced, please
106 see the commit description for the commit which added RPi3 support
107 for a workaround. Since the instructions are temporary, they are not
108 duplicated here. The VC FW enhancement is tracked in
109 https://github.com/raspberrypi/firmware/issues/579.
