f835469e19 rewrite the bootrom function header, add more operations and add ARM11 versions
- the bootrom is now mapped on the ARM11

- removed the waitClks in favor of a more canonical implementation (subs r0, r0, 4/5 + branch back)

30f0b004c2 fixed screen init, hopefully the last commmit
- properly performs gpu/backlight reset

- nukes vram so the initrd had to be moved to arm9 memory, and have its size (at least temporarily) limited to 256k

ad9a9bd5a0 - turn off the LCDs when the lid closes, and turn them back on when it's open
- reset LEDs on boot
- add code to set the notification LED
- add a PXI command to verify the NVRAM is actually online
- notify the ARM9 about the shell state through the HID thing

bf45ee3900 - added new SPI and CODEC drivers ported from linux, thanks to xerpi
- circle pad simulates dpad keys (up, right, down, left)
- raw touchscreen data is provided but currently unused
- added a simple shared memory region thing
- fixed the 10ms delay to be _after_ the backlights are turned on, thanks to profi again

as always, other stuff I probably forgot about

f5a877d00b - implemented MCU stuff and its interrupts, thanks @profi200 for the info
- moved brightness control to the ARM11
- moved HID updating to the ARM11
- moved screen init from ARM9 to the ARM11, always performed unconditionally
- removed unnecessary SCREENINIT and SET_BRIGHTNESS pxi commands

and other stuff I probably forgot about

5e56cd2f77 - refactored arm11/sys.c
- moved common.h from the ARM9 tree to the common code tree
- does proper deinit now on the ARM11 side

the bug that caused it to fail to launch some FIRMs has been fixed - it can even boot stock FIRMs

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

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
