System Startup

The Matos operating system is supposed to be started unsing a bootloader that is multiboot compatible. As such, it can receive some information about the host such as memory size, layout, video mode supported ...

When the booloader is ready, it will call the _start function as it is described as the entry point by the linker.ld. The _start function is defined in ASM under the arch/$ARCH/boot/boot.S directory. It will setup the stack and few other things like the bss section before calling the kmain() function from core/main.c
