What I actually need from you is: for the Qualcomm implementation, what
are the subarch bits defined as, and what do they correspond with - both
the VFP version, and whether they correspond with any ARM common VFP
subarchitecture version.

For the Qualcomm implementation, the subarch bits have always been 0x40
so far. And they are compatible with "VFPv3 architecture or later with
common VFP subarchitecture v3". In your table below it would be the last
row.

In ARM land, these are the possiblities - I've also listed those
platforms which I definitely know of at the moment which use the
particular version combination:

VFP version	VFP subarch
V1		-
V2		V1		Raspberry Pi
V3		V2		Marvell Dove (Cubox) (though, not ARM)
V3		NULL		OMAP3430 / OMAP4430
V3		V3
