* Porting BeagleBone to Kernel 5.10 * Fixing issue with installation for BeagleBone. This fix resolve 2 issue: 1. Conflict with AVR packages. 2. "klipper_pru" script is executed before PRU cores are ready * Adding additional steps to BeagleBone install guide. * Updating BeagleBone documentation, adding different use cases, adding buses configurations SPI, I2C, CAN, UART Signed-off-by: Oleg Gavavka <work@datalink.net.ua>
