Right, thanks for the heads up. The reason is that the current U-Boot
branch does not enable PSCI services, so the kernel does not know how to
enable and online the second core. As with the other 32-bit parts, the
PSCI nodes and properties get inserted into the DT by U-Boot, at runtime:
arch/arm/lib/psci-dt.c:fdt_psci().
It should be fairly straight-forward to enable that in U-Boot, I will try
to look into this later this week.
Cheers,
Andre
