Where is this being flagged up ?

I am fix some bug related to the panic, and these is related to the sw_reg_write src/platform/apollolake/include/platform/shim.h

static inline void sw_reg_write(uint32_t reg, uint32_t val) {         *((volatile uint32_t*)(SRAM_SW_REG_BASE + reg)) = val; }

I found in some case the SW_REG it not updated and the panic states if not sync with the IPC REGS. I would like to move SW_REG into mailbox.h and here is the volatile i hit.

Thanks Xiuli
