[ Upstream commit ebf35d8f9368816c930f5d70783a72716fab5e19 ] Before sending the data via the mailbox to the hardware, to ensure that the data accessed by the hardware is the most up-to-date, a write barrier should be added before writing to the mailbox register. The current memory barrier is placed after writing to the register, the barrier order should be modified to be before writing to the register.
