My understanding is that there are Marvell parts that are armv5+vfp.
Marvell was all armv5 until quite recently, I believe. And I think
Fedora ARM typically has been targeting Marvell.
Well I believe that is because the people running the various
buildsystems have either had reason to target Marvell or that was the
hardware they had vs any actual open discussions as to what people
wanted. I personally would like to see a build optimised for A8/A9
devices, which I realised would know a large amount of devices off the
supported list that are still shipping in quantity. Would it be hard
to support build options for a armv5 + softfp and a armv7 + hardfp
within the build infra. Debian have been having a discussion [1] that
indicates that there's the possibility of a 20+% speed improvement
which on a low power device is significant.
