Wolfvak	8a7448995f	fixed overlooked ARM9 exception handler issue where code would be dumped incorrectly, modified ARM11 exception vectors to not take an entire page of compiled code	2020-07-26 10:27:48 -03:00
Wolfvak	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)	2020-07-24 13:37:29 -03:00
Wolfvak	6487307cf0	improved mmu and gic code	2020-07-19 11:59:52 -03:00
Wolfvak	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	2020-07-18 20:25:34 -03:00
Wolfvak	fd5320b86f	- properly align ARM11 stacks and buffers ... - add very simple exception dumping for the ARM11	2019-09-29 19:53:28 +02:00
Wolfvak	a6734af45d	licensing bs	2019-06-03 02:27:43 +02:00
Wolfvak	70757e3385	- added extremely simple calibration dialog, to be replaced by something prettier/saner/safer at a later point in time ... - moved all SPI code to the ARM11 - reimplemented NVRAM reading for the new SPI interface	2019-06-03 02:27:42 +02:00
Wolfvak	bcff09a389	added a small 10ms wait before turning on the backlight, thanks to profi for reminding me of that	2019-06-03 02:27:42 +02:00
Wolfvak	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	2019-06-03 02:27:41 +02:00
Wolfvak	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	2019-06-03 02:27:41 +02:00
Wolfvak	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	2019-06-03 02:27:41 +02:00
