denandz/lpc_sniffer_tpm#2
denandz/lpc_sniffer_tpm#3

It has been tested with a TPM that were working before (AT97SC3205 from Dell Optiplex 745) and 2 TPM that were not working before: STM N18FPVMT found in Dell Optiplex 980 and a SLB9635B found in SuperMicro motherboard.

The main changes is logging of message going from address 24 to 27. I've also done a rewrite of the state machine to comply with LPC/TPM protocol.
