Hi,

I did not really understand what's the difference between -mfloat-abi=soft 
and -mfloat-abi=softfp? Does "soft" always use software floating point 
and "softfp" could use hardware floating point if a correct -mfpu is given?

And why is none of them used in Armed Slack? In my understanding it should be 
much faster than FPU emulation in the kernel.
