Quantum	80dc438fd0	Drivers: Added start of 16550 UART driver ... Seems to work well enough to take over the OpenSBI putchar TODO: Add some kind of flush() to avoid trashing data still in the FIFO when we take over from OpenSBI	2022-07-31 23:29:24 -04:00
Quantum	259d929c13	Drivers: Added Sunxi pinctrl driver ... Works well enough to set bank modes and turn on an LED Very not complete and needs more testing	2022-07-31 23:03:01 -04:00
Quantum	d100b515d6	Kernel: Disabled dtb stuff for now	2022-07-31 23:01:57 -04:00
Quantum	f9ea032b7d	Kernel/OpenSBI: Switched to stdint.h ... Not sure when I started typing cstdint but for now I want to stick to stdint.h	2022-07-31 21:32:11 -04:00
Quantum	44bfd9c4fb	Kernel: Removed left over example code	2022-07-31 21:20:48 -04:00
Quantum	ad1ac3f9d7	Common: Started writing a DTB/FDT parser	2022-06-07 01:06:02 -04:00
Quantum	4367e38f39	Kernel: OpenSBI memes ... Just making sure things work	2022-06-07 01:04:21 -04:00
Quantum	464a61102e	OpenSBI memes ... Added legacy extension Fixed typing memes by just define a sbiword_t typedef Renamed sbiret_t to SbiRet, I think i'll only use _t for typedefs Added ecall() variant that takes no additional arguments Moved opensbi includes to includes/opensbi/... kernel.cpp uses the legacy extensions instead of raw ecalls All legacy extension calls are marked as deprecated	2022-01-23 20:15:53 -05:00
Quantum	ea60891ef5	Renamed call -> ecall ... Removed old sbi call funcions in kernel.cpp	2022-01-23 15:35:18 -05:00
Quantum	94fbea02ca	Kernel: tabs -> spaces	2022-01-05 02:50:14 -05:00
Quantum	d5d92555ae	Drivers: Started OpenSBI driver ... Just ecall wrapper for now TODO: Build system changes are lazy and need to be figured out TODO: Looks like kernel.cpp was indented with tabs, fix	2022-01-05 02:47:30 -05:00
Quantum	b35d58df1f	Build System: More better ... Split code into generic, arch, and platform Made QEMU its own platform Added shitty uart upload script for lichee board until I can get fel to actually upload uboot payloads without hanging TODO: Move platform selection out of build script TODO: Move arch specific stuff from kernel to arch TODO: Common linker script for arch instead of having a copy in each platform	2022-01-04 01:50:46 -05:00
Quantum	e50fb2de2c	Initial Commit ... Mostly stolen from https://github.com/avdgrinten/riscv-toy-os Changed load address to 0x45000000 so it would run on real hardware Played around with GPIO and the watchdog	2022-01-03 19:11:49 -05:00
