hal::mpu

MPU (Memory Protection Unit) manager trait.

Legacy hooks, not the active isolated-task contract. The kernel does not call these hooks at boot or on context switches; the existing Xtensa implementation is a no-op. See crate::isolation for validated task grants.

struct TaskDescriptor {

    pub stack_base: u32,
    pub stack_size: u32,

}

Scheduler-facing task descriptor read by the MPU manager.
