Workshop: OS from scratch

The workshop aims at writing a "complete" operating system, for one of the various meanings of the word. Starting with an empty directory, we'll design and write the Makefile, linker script, assembly and C code that builds up an OS for cooperative-multitasking. At the end we'll have several tasks running on an ARM7 development board. We'll base on gcc and make, which won't be rewritten during this time slot.
