2017-08-23	Filesystem struct order	leleraffa97@hotmail.it	2	-22/+79

2017-08-23	new programmer interface for linux	Nao Pross	12	-99/+234
	there is a new program with GUI (gtk3) to send data to its avr conterpart. it needs to be tested, since there may be a few bugs in it; building a GUI was a terrible idea.
2017-08-07	implementation for avr programmer	Nao Pross	17	-0/+356
	the programmer will receive the binary in blocks of defined size by a program under sw/programmer/linux (moved from sw/linux).
2017-08-01	filesystem structure intro and docs	Nao Pross	9	-17/+106
	- new type pid_t and program management mechanism to make it easier to switch to a multitasking kernel - new memory related functions in memory.h to move, copy and manage pages - fix typos
2017-07-04	new structure for process management, structures to discuss	Nao Pross	26	-969/+328
	the idea behind kernel/include/progman.h was good but the implementation was very not unix-like, so I made a new file under kernel/include/process.h that will implement the same features other changes: - move usart register structs definitions outside of the device - remove old build files - delete boot.h and boot_loader.h (as they weren't used by anything) - change on makefile to build binary with `makebin` instead of `xxd` - new file memory.h to implement memory mapping and mmu control - new type `uint` in types.h
2017-06-23	Order and update of the struct	leleraffa97@hotmail.it	10	-218/+260
	Separation of boot and login sections Improuved program manager system
2017-06-19	libc memset, memcmpHEAD master	leleraffa97@hotmail.it	5	-24/+61
	boot improved program allocation

2017-06-15	Boot loader structures (WORK IN PROGRESS)	leleraffa97@hotmail.it	4	-0/+194
	Some Program manager structures, macros and functions (WORK IN PROGRESS)
2017-06-10	add port interface header, api still to implement	Nao Pross	3	-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.
2017-06-02	add serial interface and a few std library functions	Nao Pross	11	-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

2017-05-02	add serial device struct	Nao Pross	6	-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
2017-05-02	sysio.h libc interface	leleraffa97@hotmail.it	1	-0/+0

2017-05-02	Basic sys io setup	leleraffa97@hotmail.it	1	-0/+55

2017-05-02	fix for sdcc makefile	Nao Pross	4	-32/+122
	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	9	-101/+62
	- 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
2017-04-13	switch from GAL (pld) to M4 32/32 CPLD	Nao Pross	19	-296/+621
	add M4 32/32 CPLD datasheet new VHDL code with better control over the address space thanks to the M4 which has a 16 bit input port
