	Some Program manager structures, macros and functions (WORK IN PROGRESS)
2017-06-10	add port interface header, api still to implement	Nao Pross	1	-5/+22
	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.
2017-06-02	add serial interface and a few std library functions	Nao Pross	4	-88/+170
	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
2017-05-02	add serial device struct	Nao Pross	3	-0/+100
	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
2017-05-02	fix for sdcc makefile	Nao Pross	1	-0/+2
	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).
2017-05-02	switch to sdcc	Nao Pross	1	-0/+9
	- update of the makefile to use sdcc, since it is more popular and it's easier to insall on other computers - fix of crt0.s (old loader.asm) for the new compiler - change of the structure in the source code folder to separate betweeen libc and kernel code
