I thought Thumb-2 was only introduced with ARMv7, but it turns out it's
not the case. It has in fact been introduced in ARM1156, part of the
ARMv6 architecture.
However, this ARM1156 is not supported in Buildroot, and I have never
heard of it in any publicly available SoC.
However, this means that --enable-armv6t2 can be used for ARMv7.
Best regards,
Thomas
