Ref: v8m news
ARMv8-M Baseline:
for the most power and area constrained applications. Baseline extends ARMv6-M
used for the lowest-cost and smallest implementations
ARMv8-M Mainline:
for full-featured, highly capable embedded applications:
for more general purpose, more scalable, and supports DSP and floating-point extensions.
