A project is looking at using RTEMS on an FPGA based ARM Cortex-M1 like
the one in the Microsemi ProAsic3L development kit:

Wikipedia says the Cortex-M1 is an ARMv6M architecture.

I see that there is ARMv7M support in score, would a similar port be
needed for ARMv6M?
Is an ARMv6M close to anything in RTEMS now?
The ARMv6M has a reduced instruction set compared to ARMv7M. We have an
ARMv6M multilib, so the GCC part should be fine. You have to fix some
ARMv7M assembly code in RTEMS (not much). I tried to do this two weeks a
go, but after 10 minutes I gave up, since it had no priority for me.
