3973ce57df revert back to using Thumb code for the ARM9 binary 
leads to better density and therefore much smaller FIRM sizes

fd5320b86f - properly align ARM11 stacks and buffers 
- add very simple exception dumping for the ARM11

2f64a8046a - compile with size optimizations, reduces inst cache pressure 
- removed most of lodepng's optional features
- lodepng now uses the already existing CRC32 code instead of using its own copy
- fixed GIC interrupt priority

08b53f71e1 Fix clobbered registers on MRC/MCR/MRS/MSR C wrappers 
Previously the compiler could've optimized stores/reads to be placed outside of critical sections, etc

016eac6982 - properly set up MMU tables with caching and other fun stuff 
- maps a regular ARM-style exception vector table instead of using the bootrom vector redirection

features a ton of bugs because I'm missing something, it actually manages to boot fb3DS v1.2 and BAX fine, but fails to boot itself

2f86686388 renamed most low level functions and other stuff to fit with the current theme 
- added initial SCU twiddling
- added very untested and unusable SMP code
- fixed race condition that happened on boot
- added initial MMU code (just super basic identity mapping, no caching set up or anything)
- enabled some of the fancier ARMv6 features
- reorganized ARM11 files into their own folders
- possibly more stuff I'm forgetting about

e70b8ab116 - unified CPU/cache header that works on C and asm code 
- added legacy boot PXI command that allows power savings on ARM11

987b820c4a beginning of better ARM11: 
- moved I2C code to the ARM11 (with an ugly hack that MUST be fixed)
- reworked the PXI protocol to have lower latencies and remove any potential async support
