Asahi Linux progress report

Not quite - the Intel implementation runs on the ME, which is on the chipset for non-SoC devices. AMD's implementation is on the PSP, which *is* on the CPU package. But yes, assuming the system vendor has wired it up, you don't need a physical TPM for TPM functionality these days. In some ways, it's even preferable - the LPC bus that discrete TPMs are attached to is extremely easy to interpose, which is far less true for fTPMs.
