2019-12-18	WIP Revamp ChaCha20 seedingln/cc20rng-revamp	Linus Nordberg
	- chacha20_prng_block() uses counter in the state struct - chacha20_setup() replaces chacha20_prng_reseed() and fills the whole state struct, fixing a bug where only half of the key was being set; as a result of 'counter' being set, a state struct filled with entropy from the TRNG makes reseeding occur after a random number of rounds instead of after a fixed 2^32-1 rounds - decrementing of the block counter is done in chacha20_prng_block() - chacha output is copied to buf _after_ the interrupt driven transmission of buf to UART has finished, to stop the race between reading and refilling of buf
2019-12-18	Formatting cc20rng	Linus Nordberg
	Keep indentation level 2 in main.c to minimise changes.

2016-11-21	add RNG using ChaCha20 as CSPRNG	Fredrik Thulin

2015-06-28	Enable dual USART output functionality.	Fredrik Thulin
	In other words, enable the USART connected to the serial port on the Raspberry Pi GPIO header. Sending a newline to either USART directs the generated entropy to that USART.
2015-06-28	Remove trailing whitespace and DOS line endings.	Fredrik Thulin
