## Summary In the current NuttX MPU implementation, it is not possible to reconfigure a region that has already been set. Therefore, the purpose of this MPU upgrade is to enhance the ability of NuttX MPU to more accurately adjust the region. The main interfaces are ``` void mpu_modify_region(unsigned int region, uinptr_t base, size_t size, uint32_t flags); void mpu_clear_region(unsigned int region). ``` And change the g_region at the beginning to a bitmap to indicate whether each region has been allocated or not. ## Impact update mpu for: armv7m armv8m armv7r arm64 xtensa ## Testing Local test pass -- This is an automated message from the Apache Git Service.
