This is probably due to the fact that the PSCI command encodings for
Highbank expected by the kernel are mismatched to the ones in QEMU. I
had some patches to change them, but once I got the PSCI right, the
boot hung (might be just extreme slowdown like you describe) and I
never got the time to fully debug it. SO there is a good chance
Highbank has the same bug.
