108* @brief Data Memory Barrier, Data Synchronization Barrier
109*
110*
111* @par Description: These functions do nothing on x86 side. But on arm platforms,
112*
113* Data Memory Barrier acts as a memory barrier. It ensures that all explicit
114* memory accesses that appear in program order before the DMB instruction are
115* observed before any explicit memory accesses that appear in program order
116* after the DMB instruction. It does not affect the ordering of any other
117* instructions executing on the processor
118*
119* Data Synchronization Barrier acts as a special kind of memory barrier. No
120* instruction in program order after this instruction executes until this instruction
121* completes. This instruction completes when:
122*       1. All explicit memory accesses before this instruction complete.
123*       2. All Cache, Branch predictor and TLB maintenance operations before
124*       this instruction complete.
125*
126* @param[in] void
127*
128* @returns  void
129*
130* @remarks none
