Add RMC-RA4M1(R7FA4M1AB3CFP)
https://www2.himdx.net/mcr/product/download.html#ra4m1

"rmc_ra4m1_20.json" was created based on "uno_r4_minima.json".
"svd_path" is the same as R4 MINIMA, so you may need to modify it if you want to debug. (I haven't checked this.)

Hi @todateman, thanks for the PR. I'm afraid your manifest won't work as you expect, mainly because there is no such variant rmc_ra4m1_20 in the Arduino core for Renesas devices. You could use the same variant as for the R4 MINIMA board just to compile the code, but I believe the pinout of RMC-RA4M1 differs significantly from R4 MINIMA which will lead to non-obvious issues.

Hi, @valeros
Thank you for confirming.

I forked a repository that includes rmc_ra4m1_20 in the variants directory of ArduinoCore-renesas.

You may be able to approve my pull request after the pull request to ArduinoCore-renesas is approved.

Great, your PR will be merged, once a new stable version of ArduinoCore-renesas is released.
