Hi Eddie,
Thanks for the cleanup! Unfortunately this doesn't compile with EFI selected, but in general it looks pretty good.
Thanks, yes I forgot to remove tcg2_pcr_read

Add TPM2 functions to support boot measurement. This includes starting up the TPM, initializing/appending the event log, and measuring the U-Boot version. Much of the code was used in the EFI subsystem, so remove it there and use the common functions.

Can you please point to the spec containing what this implements? I am still not sure why the identifiers and filenames have EFI in them.
Yes. Primarily implementing this specification: https://trustedcomputinggroup.org/wp-content/uploads/TCG_ServerManagDomainFW...
See chapter 9, event logging, which mentions the TCG_EfiSpecIdEvent as the first event in the event log.
OK thank you for the reference. What is the difference between that and TCG_PCClientPCREvent?
