I think for the infracfg part I figured it out:

#define	INFRA_TOPAXI_PROTECTEN_SET	0x2a0
#define	INFRA_TOPAXI_PROTECTEN_CLR	0x2a4
#define	INFRA_TOPAXI_PROTECTEN_STA1	0x228

#define	INFRA_TOPAXI_PROTECTEN_1_SET	0x2a8
#define	INFRA_TOPAXI_PROTECTEN_1_CLR	0x2ac
#define	INFRA_TOPAXI_PROTECTEN_STA1_1	0x258

#define	INFRA_TOPAXI_PROTECTEN_MCU_SET	0x2d4
#define	INFRA_TOPAXI_PROTECTEN_MCU_CLR	0x2d8
#define	INFRA_TOPAXI_PROTECTEN_MM_STA1	0x2ec

Weiyi, can you still provide the register names for the SMI?

Thanks in advance!
