Of course there was armv6 support in freebsd 10. 2. I never proposed eliminating armv6/rpi support, I was always about adding armv7 as its own arch. I did once propose renaming armv6hf to armv6 without bothering to do the magic softfp compatibility thing you did, maybe that's what you're remembering (basically using tier-2 status freedom to break ABI in the middle of a released branch). Of course I support the new proposol to create an armv7 arch. :) -- Ian
