* altos/chaoskey: use both halves of the CRCKeith Packard2017-02-20
| | | | | | | | When pulling 16 bits from the 32-bit crc, instead of just using the low bits, xor the two halves together. This appears to even out the number of zero and one bits. Signed-off-by: Keith Packard <keithp@keithp.com>

* altos/stmf0: Add CRC driverKeith Packard2015-01-27
Sets up the stm32f0 CRC hardware, exposing inline functions to access it. DMA access is possible, but usbtrng can't use that. Signed-off-by: Keith Packard <keithp@keithp.com>
