Sönke Holz	da33e2a564	Kernel/riscv64: Add MMU initialization code ... We initialize the MMU by first setting up the page tables for the kernel image and the initial kernel stack. Then we jump to a identity mapped page which makes the newly created kernel root page table active by setting `satp` and then jumps to `init`.	2024-01-12 16:46:46 -07:00
Sönke Holz	27860cfaa2	Kernel/riscv64: Add a basic trap handler to pre_init ... This trap handler uses the SBI to print an error message via a newly introduced panic function, which is necessary as `pre_init` is running identity mapped. Also add a header file for `pre_init.cpp` as we wan't to use the panic and `dbgln` function in the MMU init code as well.	2024-01-12 16:46:46 -07:00
