[U-Boot] ARMv8 switching CPUs into EL1

L.S.!

On a Xilinx ZynqMP-based platform with u-boot running in Aarch64 mode in EL2, after booting a Linux kernel in EL1 using CONFIG_ARMV8_SWITCH_TO_EL1, Linux throws a warning that the CPUs have started in inconsistent modes ("CPU: CPUs started in inconsistent modes"). Indeed, only the first core on which U-boot was running is switched to EL1 at this point.

Is this a bug or a not completely supported feature in U-boot or can this warning actually be safely ignored under certain circumstances?

Kind regards,

Mels
