2026-04-06sifive_dev_platform: Set default MMIO region when SmePMP is enabledYu-Chien Peter Lin
Set a default MMIO region with a single SmePMP entry, which allows us to save entries for M-mode only devices. The default entry has M-/S-mode shared permission, so system-level resource protection, such as RISC-V World extension and WorldGuard checker, will be introduced to protect M-mode only region access from lower privilege modes.
