The marshaling code is a port of the coreboot patch https://chromium-review.googlesource.com/353915. The only supported commands at this time are NV_read and NV_write. The tlcl layer includes functions necessary to satisfy compilation requirements of rollback_index.c, functions to lock spaces and clear TPM are not yet implemented, they just report being invoked. The missing functions implementation is coming, but even without it it is possible to boot Chrome OS with firmware and kernel rollback counters maintained in the TPM NVRAM.
