They initially told people that armv6 with vfp will be included in aarch32..
But then,
When they created aarch32( the real one...armv7...it has a vfpv3 at least I believe, vector extensions were droped in favour of SIMD NEON 1.0.. ), that idea was droped..
So armv6 could not be in aarch32.. because aarch32 or armv7, is a new architecture..
So compilers for Hardfloat target armv7 only,
And not armv6( for which some processors have vfp.. )
So you end with armel for armv6 with vfp( that's why I compiled kernel with hardfloat support, but the userspace is Devuan, so armel.. ).
Also,
Armel targets ARMv5T, ARMv6( unfortunatly even processors armv6 with vfp, are in that group of arm32 != aarch32 )
