* @brief Data Memory Barrier, Data Synchronization Barrier
*
*
* @par Description: These functions do nothing on x86 side. But on arm platforms,
*
* Data Memory Barrier acts as a memory barrier. It ensures that all explicit
* memory accesses that appear in program order before the DMB instruction are
* observed before any explicit memory accesses that appear in program order
* after the DMB instruction. It does not affect the ordering of any other
* instructions executing on the processor
*
* Data Synchronization Barrier acts as a special kind of memory barrier. No
* instruction in program order after this instruction executes until this instruction
* completes. This instruction completes when:
*       1. All explicit memory accesses before this instruction complete.
*       2. All Cache, Branch predictor and TLB maintenance operations before
*       this instruction complete.
*
* @param[in] void
*
* @returns  void
*
* @remarks none
