* @brief Enable early entropy source for RNG
*
* Uses the SAR ADC to feed entropy into the HWRNG. The ADC is put
* into a test mode that reads the 1.1V internal reference source and
* feeds the LSB of data into the HWRNG.
* into a test mode that reads an internal reference voltage and
* constantly feeds the LSB of data into the HWRNG. Consult the
* SoC Technical Reference Manual for more information.
*
* Can also be used from app code early during operation, if entropy
* is required before WiFi stack is initialised. Call this function
* from app code only if WiFi/BT are not yet enabled and I2S and SAR
* ADC are not in use.
* Can also be used from app code early during operation, if true
* random numbers are required before WiFi stack is initialised.
* Call this function from app code only if WiFi/BT are not yet
* enabled and I2S and ADC are not in use.
*
* Call bootloader_random_disable() when done.
