*Debian*'s armhf is configured to use Thumb-2, but you could rebuild

With actual RPi hardware still being 6 to 8 weeks out, would a Freescale
i.MX535 Quick Start board allow such benchmarking? I presume an armel
install of Debian and compiling certain packages with VFP2 optimizations
would be pretty straight forward. Is armhf in such a state that it would be

BTW my gcc man page has an armv6t2 -march= target, so I suspect there
are some ARMv6 CPUs with Thumb-2.
You still can't run ARMv7 Thumb-2 code an an ARMv6t2 core. The same way you
can't run ARMv7 ARM code on an ARMv6 core. THe only ARMv6t2 implementation I
know of is the arm1156 (which

For all intents and purposes, this *is* a new port. This can't just be done

Debian is expecting Pi users, like all pre-v7 hardware
