Ville Juven 8a4881c4e5 Implement CONFIG_BUILD_PROTECTED with MMU ... NOTE: THIS ONLY WORKS WHEN KERNEL RUNS IN M-MODE FOR NOW This frees the PMP for other use, e.g. HART memory separation. The page tables are statically allocated, 1 per level. This feature is now behind CONFIG_MPFS_USE_MMU_AS_MPU, because only the MPFS target supports this (others are not tested). If the MMU is used for memory separation within a HART, the PMP must still be configured to allow user access to the memory mapped for the HART, because PMP *rekoves* access by default. At this point all of the user memory as well as the kernel RAM are opened. A more flexible solution for PMP configuration will follow.		2022-01-25 20:22:34 +08:00
