Hardware floating point support?

I'm porting an application from an x86 Atom to an i.MX53 QSB for a wave energy project.


The i.MX53 QSB optimizes the transfer of mechanical power into electrical current to charge

batteries.  Using a i.MX53 QSB should drop our HOTEL load from 12 watts to 2 watts


Having worked through installing a SATA drive and getting a cross tool chain working

with Eclipse CDT/RSE, I have stumbled into another potential pot hole.


Our existing app makes extensive use of floating point arithmetic.  I just discovered that

Linux kernels come into two flavors for this class of ARM processors.  A  "armhf" kernel

seems to imply support for hardware floating point.


Does the kernel on the micro-SD shipped with i.MX53 QSB support floating point natively? 

We need just standard IEEE-754 double precision floating point.


If not, is there kernel and tool chain with hardware floating point supported?  Where

can it be downloaded?
