[libcpu] rv64: support for ARCH_REMAP_KERNEL (#9067)

2024-06-18T03:15:59Z

* [libcpu] support for ARCH_REMAP_KERNEL These changes introduce support for the ARCH_REMAP_KERNEL configuration, which isolates kernel space in high virtual address regions. This feature is necessary to enhance memory protection and management by segregating user and kernel spaces more effectively. Changes: - Updated conditional macros to check for ARCH_REMAP_KERNEL instead of ARCH_KERNEL_IN_HIGH_VA in board initialization files to reflect the new configuration option. - Modified qemu-virt64-riscv Kconfig and SConstruct files to include and utilize ARCH_REMAP_KERNEL. - Created a new linker script `link_smart.lds` for smart linking in qemu-virt64-riscv. - Updated rtconfig.py to use a more flexible execution path setup. - Enhanced user address space definitions in `lwp_arch.h` to support the new virtual address mappings. - Adjusted kernel memory initialization and mapping logic in `c906/mmu.c` and `virt64/mmu.c` to account for high virtual address regions. - Added Kconfig option to enable ARCH_REMAP_KERNEL for RISCV64 architectures. - Enhanced memory setup functions to support new mapping scheme, including updates to early page table setup and address relocation logic. These modifications ensure that the system can utilize high memory addresses for the kernel, improving memory isolation and system stability.
