In include/asm-ppc/processor.h the definitions for the Time Base Upper and Lower registers are incorrect for the PPC440GX.
#define SPRN_TBRL 0x10D /* Time Base Read Lower Register */ #define SPRN_TBRU 0x10C /* Time Base Read Upper Register */ #define SPRN_TBWL 0x11D /* Time Base Write Lower Register */ #define SPRN_TBWU 0x11C /* Time Base Write Upper Register */
i fixed this in my own code by adding the following ifdef:
#ifdef CONFIG_440GX #define SPRN_TBRL 0x10C /* Time Base Read Lower Register */ #define SPRN_TBRU 0x10D /* Time Base Read Upper Register */ #define SPRN_TBWL 0x11C /* Time Base Write Lower Register */ #define SPRN_TBWU 0x11D /* Time Base Write Upper Register */ #else #define SPRN_TBRL 0x10D /* Time Base Read Lower Register */ #define SPRN_TBRU 0x10C /* Time Base Read Upper Register */ #define SPRN_TBWL 0x11D /* Time Base Write Lower Register */ #define SPRN_TBWU 0x11C /* Time Base Write Upper Register */ #endif
