Cortex M1 is ARMv6 and Cortex A9 is ARMv7. The RS userspace targets 
ARMv5, so yes, it should run on both of those.

Some SoC vendors tend not to be particularly open about such things 
until you actually buy the dev kit, but it is a virtual certainty you 
will get a supported kernel they have cooked up for the device with it - 
otherwise nobody would buy them.

Some SoC vendors are very good at pushing things upstream, too, e.g. 
Marvell.
