| * add port interface header, api still to implementNao Pross2017-06-103-25/+31
| | | | | | | | | | | | fix for bug in usart.c, in function usart_write() that checked the trasmission_empty register at the wrong time causing it to overwrite the buffer.
| * add serial interface and a few std library functionsNao Pross2017-06-0211-90/+336
| | | | | | | | | | | | | | | | | | | | | | | | changes in usart: - new functions to setup the serial comunication settings such as baudrate, parity and stop bits - init function with most common values - transmit and receive functions each with a wrapper to send data blocks changes in libc: - new file stdio.c with basic implementation of putch, printf still a prototype - new file string.c with memcpy() function
| * new file coding_rules.txt to have a consistent coding styleNao Pross2017-05-031-0/+120

| * add serial device structNao Pross2017-05-026-14/+104
| | | | | | | | | | | | | | | | | | other changes: - change from main() to kmain() in crt0.s and kernel.c - new file devices.h to define all address locations for devices - new data type - register_t as volatile uint8_t for registers in devices - size_t from libc

| | | | | | | | | | | | | | | | | | fix for the old makefile, because it could't compile more than one source file. new libc directory with mem.c to start implementing the standard C library (or at least the part we need).
