PS19, Line 9: coreboot is made to export the range allocated for the log.
Sorry, I do not understand this sentence. This patch only changes the cbmem utility, doesn’t it?

PS19, Line 12: 
1.  Could you please give some more background on the implementation. You check CBMEM for certain fields (`CBMEM_ID_TCPA_TCG_LOG`)?

2.  Pleases add a TEST= line with the output printed by the new code.

`ARRAY_SIZE(tpm_event_types)` could also be printed.
