Makes sense > TPM core should register HWRNGs when chips are ready. The main thing I've wanted from the TPM RNG is 'add_early_randomness'.. We can certainly provide a TPM interface to hwrng, it seems reasonable. Excep that we already have a user api in /dev/tpm to access the tpm RNG, is the duplication a problem?
