* @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.
|
|
*
|
|
* 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.
|
|
*
|
|
* Call bootloader_random_disable() when done.
