  tpm: Enable TCG_TPM2_HMAC by default only for X86_64 (2024-05-28 13:14:29 +0300)

----------------------------------------------------------------
Hi,

This PR fixes two unaddressed review comments for the HMAC encryption
patch set. They are cosmetic but we are better off, if such unnecessary
glitches do not exist in the release.

The priority part of this PR is enabling the HMAC encryption by default
only on x86-64 because that is the only sufficiently tested arch.

Finally, there is a bug fix for SPI transfer buffer allocation, which
did not take into account the SPI header size.

BR, Jarkko
