* | Move test units to z80/tests, and drivers are now statically linkedNao Pross2017-10-0561-1148/+907
| | | | | | | | | | | | | | | | Makefiles for the test units were getting messier, so now drivers (that need to be tested) are statically compiled in their own folder under z80/drivers. The kernel makefile and is now broken since everything has been moved.

| | | | | | | | | | | | | | | | | | | | | | | | 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.

* | new structure for process management, structures to discussNao Pross2017-07-0426-969/+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
