https://review.coreboot.org/c/coreboot/+/80453/comment/49c13f86_67d90e00 : PS1, Line 9: We can assume that platforms, which select HAVE_INTEL_PTT, will not : have any other CRB TPM than PTT. Probably the dTPM could use CRB interface if it supports CRB besides FIFO. So basically, this is just an interpretation or, rather putting the interpretation to better use.
HAVE_INTEL_PTT help section says:
Activate if your platform has Intel Platform Trust Technology like Intel iTPM and you want to use it.
