Entropy pool gathers environmental noise from device drivers, user-space, etc., and returns good random numbers, suitable for cryptographic use. Based on entropy pool design from *BSDs and uses BLAKE2Xs algorithm for CSPRNG output. Patch also adds /dev/urandom support for using entropy pool RNG and new 'getrandom' system call for getting randomness without file-descriptor usage (thus avoiding file-descriptor exhaustion attacks). The 'getrandom' interface is similar as 'getentropy' and 'getrandom' available on OpenBSD and Linux respectively. |

ADXL345 ======= The ADXL345 accelerometer can operate in I2C or SPI mode. To operate in I2C mode just connect the CS pin to Vddi/o. In order to operate in SPI mode CS need to use connected to microcontroller, it cannot leave unconnected. In SPI mode it works with clock polarity (CPOL) = 1 and clock phase (CPHA) = 1. MPL115A ======= This driver has support only for MPL115A1 (SPI), but support to MPL115A2 (I2C) can be added easily.
