Use this new Kconfig instead of OF_BOARD, so we know for sure which boards obtain their devicetree from a prior stage. Leave sandbox alone since it does not. Also don't touch xilinx_versal_virt since it does not have a specific TARGET Kconfig. This option implies OF_BOARD for now, but with future work standard passage may be used instead.

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:

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.
