Renesas has recently (a few years ago) started selling Arm Cortex M
chips, and as I heard at a recent seminar on these, you can download a
free, fully functioning IAR dev system that's solely for the  Renesas

I suppose you could redo a bunch of the support code for another
maker's ARM Cortex M chips, but 1. that would be a lot of work, and 2.
it goes totally against the license for these things.

I've written a series of equates for various registers and I/O ports
for smaller parts (68HC11) before writing much of the "real" code
because I saw where I had a need for it, but that was almost 30 years
ago when software (assembler!) vendors didn't always include such
things. These Cortex M things are one or two orders of magnitude
bigger as far as the number of peripherals and number of I/O registers
per peripheral.
