This is actually pretty much exactly what I see in the working OVMF
TPM2 @ 0x0000000000000000
0000: 54 50 4D 32 4C 00 00 00 04 DB 42 4F 43 48 53 20 TPM2L.....BOCHS
0010: 42 58 50 43 54 50 4D 32 01 00 00 00 42 58 50 43 BXPCTPM2....BXPC
0020: 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................
0030: 06 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................
0040: 00 00 01 00 00 60 BE 7F 00 00 00 00 .....`......
