This command should be supported for PSCI 1.0. Current code results in this message from the kernel: "PSCIv65535.65535 detected in firmware."
This will mess up a kernel check of the PSCI version. Currently the kernel only cares if the version is at least 1.0 so it doesn't break anything, as the incorrect version and correct version are both >= 1.0, but as soon as a check for > 1.0 goes in it will fail.
