feat: libcpu/risc-v: unify low-level bringups

2024-09-11T22:06:51Z

This patch consolidates the separated architecture-specific code for rv64 (virt64 and c906) under a more unified approach. The changes aim to enhance maintainability and code reuse, reducing duplication between these two architectures while adding small improvements in porting compatibility. Changes: - Modified build scripts (SConscript) for both virt64 and c906 to remove ASID and vector dependencies when not required. - Updated c906's sbi.c and sbi.h to use standard integer types (uint32_t) and include the missing header. - Unified inline function declaration for `sbi_call` across both c906 and virt64 using `rt_inline`. - Disabled FPU and vector in c906's startup assembly file, aligning it with the virt64 handling. - Corrected syscall handler type definitions in c906 for consistency.

feat: libcpu/risc-v: unify interrupt & IO on rv64

2024-09-11T22:06:51Z

This patch aims to unify the two currently separated RISC-V 64-bit architecture ports, 'virt64' and 'c906', into a single generic 'common64' port. The changes include renaming files and updating includes to use a unified 'interrupt.h' header, as well as making adjustments to IO and trap handling to be more consistent between the two architectures. Changes: - Renamed 'rt_interrupt.h' to 'interrupt.h' and updated includes accordingly. - Unified IO register access functions in 'riscv_io.h'. - Added 'opcode.h' for portable assembly support. - Updated 'plic.c' and 'plic.h' to handle interrupts in a unified manner. - Modified 'trap.c' to handle exceptions and interrupts consistently for 'rv64'.

feat: libcpu/risc-v: unify mmu related works

2024-09-11T22:06:51Z

These changes are designed to standardize the memory management across 'virt64' and 'c906', ensuring efficient handling of address spaces and page tables. Changes: - Creation of ASID management files (`asid.c`) for both 'c906' and 'virt64' architectures, which is essential for maintaining stability. - Extensive updates to the MMU configuration and handling in `mmu.c` and `mmu.h` files. - Addition of functions to manage ASID allocation and switching of page tables. - For c906, accommodated the early memory setup to the one from virt64.
