Agree. I think adding armv{4,5,6,7...} is the most clean solution.

I was not able to express my point, sorry. Of course, the right place
for them is arch/arm/cpu/armv7/start.S. My concern was related to this
SOC, as it seems it steals armv7 code but it is not armv7. Then changes
in start.S, that fixes real problems for armv7, can break this Vybrid.
But the reason is that Vybrid initialization should not be taken from
arch/arm/cpu/armv7/start.S.

Best regards,
Stefano
