MYNEWT-581; kernel/os - support hw fpu in context switches for cortex-m4.
> support hw floating point with cortex-m4

> Key: MYNEWT-581
> URL: https://issues.apache.org/jira/browse/MYNEWT-581
> Project: Mynewt
> Issue Type: Improvement
> Reporter: Marko Kiiskila
> Assignee: Marko Kiiskila
> Fix For: v1_0_0_rel
>
>
> Add a syscfg knob for this; hw floating point computations are faster, but
> enabling FPU eats more power/stack space.
> During context switching, swap in/out floating point registers.
> Pass appropriate parameters to compiler to enable floating point instruction
> generation.
