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.
