[Buildroot] [PATCH 0/6] arch/ar: add cortex-m7, and cortex-M FPUs

[Yann E. MORIN <yann.morin.1998@free.fr>]

Hello All!

This small series adds support for cortex-m7, and support for using the
FPUs present in some cortex-M cpu, like the FPv4 on cortex-m4, or the
FPv5 on cortex-m7.

It has not been runtime-tested by lack of hardware, but it can at least
build a toolchain and busybox [0], which is basically all that we can
expect to run on such CPUs anyway.

Yann E. MORIN.
