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.

50 Support for all ARM1176-/BCM2835-based Raspberry Pi variants, such as
51 the RPi Zero model W.
52
53 This option assumes the VideoCore firmware is configured to use the
54 mini UART (rather than PL011) for the serial console. This is the
55 default on the RPi Zero W. To enable the UART console, the following
56 non-default option must be present in config.txt: enable_uart=1.
57 This is required for U-Boot to operate correctly, even if you only
58 care about the HDMI/usbkbd console.

66 Support for all BCM2836-based Raspberry Pi variants, such as
67 the RPi 2 model B.
68
69 This option also supports BCM2837-based variants such as the RPi 3
70 Model B, when run in 32-bit mode, provided you have configured the
71 VideoCore firmware to select the PL011 UART for the console by:
72 a) config.txt should contain dtoverlay=pi3-miniuart-bt.
73 b) You should run the following to tell the VC FW to process DT when
74 booting, and copy u-boot.bin.img (rather than u-boot.bin) to the SD
75 card as the kernel image:
76
77 path/to/kernel/scripts/mkknlimg --dtok u-boot.bin u-boot.bin.img

105 Support for all BCM2837-based Raspberry Pi variants, such as
106 the RPi 3 model B, in AArch64 (64-bit) mode.
107
108 This option assumes the VideoCore firmware is configured to use the
109 mini UART (rather than PL011) for the serial console. This is the
110 default on the RPi 3. To enable the UART console, the following non-

112 required for U-Boot to operate correctly, even if you only care
113 about the HDMI/usbkbd console.
114
115 At the time of writing, the VC FW requires a non-default option in
116 config.txt to request the ARM CPU boot in 64-bit mode:
117 arm_control=0x200
118
119 The VC FW typically provides ARM "stub" code to set up the CPU and
120 quiesce secondary SMP CPUs. This is not currently true in 64-bit
121 mode. In order to boot U-Boot before the VC FW is enhanced, please
122 see the commit description for the commit which added RPi3 support
123 for a workaround. Since the instructions are temporary, they are not
124 duplicated here. The VC FW enhancement is tracked in
125 https://github.com/raspberrypi/firmware/issues/579.
