Dauntless/D2 is the name of the next TPM chip designed by Gchips, after Haven/H1.  So yes, Dauntless is new hardware.

Dauntless will run a new Ti50 firmware based on TockOS and the Rust language.  This will supplant the Cr50 firmware based our own ECOS and C language.

In theory, you could port Ti50 firmware to the existing H1 chip, but there would be little point in doing so.
