This is a Cortex A53 isn't it? So it's ARMv8. I thought the issue is
that it's actually a 64bit system but you only have a 32bit
bootloader, firmware etc?

Off-topic but related:  Another MediaTek spin off, SigmaStar, seems to
have done exactly the same thing. Cortex A53 chip running as a 32bit
system to avoid having to fix their software. I'm interested to see if
this makes it into arm or arm64. :)

Cheers,

Daniel
