Sergii Dmytruk 6da62684de util/cbmem: add parsing of TPM logs per specs ... CBMEM can contain log in different forms (at most one is present): - coreboot-specific format (CBMEM_ID_TPM_CB_LOG exported as LB_TAG_TPM_CB_LOG) - TPM1.2 format (CBMEM_ID_TCPA_TCG_LOG) - TPM2 format (CBMEM_ID_TPM2_TCG_LOG) The last two follow specifications by Trusted Computing Group, but until now cbmem couldn't print them. These formats were added not so long ago in: - commit 4191dbf0c9 ("security/tpm: add TPM log format as per 1.2 spec") - commit 53db677586 ("security/tpm: add TPM log format as per 2.0 spec") These changes make cbmem utility check for existence of TPM1.2/TPM2 logs in CBMEM and add code necessary for parsing and printing of their entries.
