More assembly cleanup.

hardware.c --> system.c. Call systemInit() before main().

Extend ARM9 heap on N3DS.

Make asm code less cluttered. Changed magic to match name.

Use unified pools for data in .s files.

Small adjustments. Enable data cache for DSP mem/AXIWRAM on ARM9.

Enable MPU before clearing the bss.

Loosen MPU config for future changes.

Added license to all sources. Dir structure cleanup.

Heap start is automatically setup.

Nitpicking/consistency.

Nitpicking + fixes in .s files.

That msr instruction change did not do what i expected.

Init stack pointers of exception modes on ARM11.

Allow recursive interrupts. Reworked exception handling a bit to support non-user/system exceptions.

Improve assembly files a bit.

Proper IRQ stack handling on ARM9.

Switched back to devkitARM makefiles. Makefile now detects if the target FIRM file is outdated.

Added automatic version parsing based on git tags.

Move fastboot magic to start of ARM9 section. Change ARM11 cache code back since it was not the issue in the first place.

Unfinished argc/v support for FIRM loading.

nitpicking

stuff

Damn copy and paste fail.

2 little mistakes i noticed recently.

Merge cpu.s back into start.s.

Properly init other CPU mode stacks.

Whitespace fixes so it looks better on Gitlab.

Big refactor. Updated fatfs, changed the dir structure, added MMU support to the ARM11 side and lots of small changes.

A lot of changes and little bug fixes.
