Marcin Wojtas 4ee7d3b011 Allow using TPM as entropy source. ... TPM has a built-in RNG, with its own entropy source. The driver was extended to harvest 16 random bytes from TPM every 10 seconds. A new build option "TPM_HARVEST" was introduced - for now, however, it is not enabled by default in the GENERIC config.
