I'm writing preliminary OpenOCD support for the MSPM0 family.
Unfortunately, I can't find any information in the datasheet, SDK docs, or TRM about how to send commands into the DSSM, nor what commands to use to perform Mass erase and Factory reset.
The closest I found was the m0 gel file, but it just executes on-DAP as a high level command.
Even just "write these bytes to DSSM_TXD and poll DSSM_RXD until a bitmask matches" would be enough information for me to proceed!
