It appears you need to have
fdt_copy_node_names=/cpus:/psci
fdt_copy_src_addr=0x83080000
in your U-Boot configuration. This is documented somewhere in the middle of
http://elinux.org/Jetson/TX1_Upstream_Kernel.
I can confirm that this works with u-boot from L4T R24.2.1.
However, it doesn't work with mainling u-boot (grepping for fdt_copy_
doesn't show anything in the source code).
Does anyone know how to get all 4 CPUs working with mainline u-boot?
Thierry, Jon, do you know?
The "fdt_copy" feature of U-Boot isn't upstreamed since I thought it was
only required to boot the L4T kernel, not mainline. We're also reworking
L4T so this feature won't be needed there either, so I don't expect to
upstream "fdt_copy".
