The TPM has a hardware random number generator that could be used as a source of entropy in rng-tools.
Which device? /dev/tpm0, /dev/tpm1, /dev/tpm2... ?? It requires configuration anyway.

currently it is /dev/tpm0, If /dev/tmp0 fails we dont use the tpm. There is no configuration required.
I think you've just made my point clear: it needs configuration.
How many systems have you seen with multiple TPMs present? Personally, I've seen none.
why do we still not have this cool functionality? Many systems ship with a TPM with a good fast RNG. These systems run out of entropy completely needlessly today.
I agree, we need accelerated crypto
