Most boards use don't use ACPI but device-trees for calling
the operating system.
We try to keep our device-trees in sync with Linux.
The device-tree available under $fdtcontroladdr should be
usable to boot the OS.
We should avoid anything that could lead now or in the future
to a conflict with the the OS usage of the device tree nodes.

Please, use in the example a compatibility string that is
unique to U-Boot.

How about: "uboot,sandbox-sysinfo"?

Best regards

Heinrich
