Re: [PATCH v4 3/3] tpm: get tpm event log from bloblist

Get tpm event log from bloblist instead of FDT when bloblist is enabled and valid from previous boot stage.

As a fallback, when no event log from previous stage is observed and no user buffer is passed, malloc a default buffer to initialize the event log.

Signed-off-by: Raymond Mao raymond.mao@linaro.org

Changes in v2

• Remove patch dependency.
• Remove the fallback to FDT when BLOBLIST is selected.

Changes in v3

• Malloc an 8KB buffer when user eventlog buffer does not exist.

Changes in v4

• Replace the default eventlog size with TPM2_EVENT_LOG_SIZE.
