86 This option also supports BCM2837-based variants such as the RPi 3
87 Model B, when run in 32-bit mode, provided you have configured the
88 VideoCore firmware to select the PL011 UART for the console by:
89 a) config.txt should contain dtoverlay=pi3-miniuart-bt.
90 b) You should run the following to tell the VC FW to process DT when
91 booting, and copy u-boot.bin.img (rather than u-boot.bin) to the SD
92 card as the kernel image:
93
94 path/to/kernel/scripts/mkknlimg --dtok u-boot.bin u-boot.bin.img

131
132 At the time of writing, the VC FW requires a non-default option in
133 config.txt to request the ARM CPU boot in 64-bit mode:
134 arm_control=0x200
135
136 The VC FW typically provides ARM "stub" code to set up the CPU and
137 quiesce secondary SMP CPUs. This is not currently true in 64-bit
138 mode. In order to boot U-Boot before the VC FW is enhanced, please
139 see the commit description for the commit which added RPi3 support
140 for a workaround. Since the instructions are temporary, they are not
141 duplicated here. The VC FW enhancement is tracked in
142 https://github.com/raspberrypi/firmware/issues/579.

182 Also, due to a bug in firmware, switching to 64bit mode doesn't
183 happen automatically based on the kernel's image filename. See
184 https://github.com/raspberrypi/firmware/issues/1193 for more details.
185 Until that is resolved, the configuration (config.txt) needs to
186 explicitly set: arm_64bit=1.
