Please look at txt_verify_platform() function in verify.c there are few
checks that TBOOT does to verify if platform is properly configured for
measured launch.

You can also look at does_acmod_match_platform() in acmod.c, to see how
TBOOT checks if SINIT ACM matches platform. It compares CPU and PCH IDs
from SINIT header to actual values.

Thanks,
Lukasz
