Subject: [PATCH v4 00/11] tpm: Support using TPM1 and TPM2 from a single API
Date: Sat, 6 Feb 2021 14:23:31 -0700 [thread overview]
Message-ID: <20210206212343.3567308-1-sjg@chromium.org> (raw)
At present if an application wants to be written so it can work with
both TPMv1.2 and TPM2 it must use two different APIs. This is inconvenient
since it requires adding code to deal with the mismatch between the two.
It would be better to have a common API that all boards could share.
This series provides a simple API the covers some basic features and
implements them for both TPM standards.
Changes in v4:
- Use uint type for size and explain it in the commit message
- Drop unnecessary update of offset
Changes in v3:
- Add a comment to the offset and fix up the value
Changes in v2:
- Add comments for the offset value
- Add definition of TPM2_RC_NV_DEFINED return code
Simon Glass (11):
tpm: Don't include cr50 in TPL/SPL
tpm: Use logging in the uclass
