I can't reproduce this, including with your kernel binary, which suggests that this an issue with your FVP usage and firmware.

How are you invoking the FVP, what firmware are you using and how is it configured?

This is an undefined instruction, my first thought there would be that you have some feature enabled for the kernel which requires enablement at EL3 but your EL3 firmware is not configured to enable it.

This is where the undef came from.
