* XScale coprocessor support.
2001-04-18 matthew green <mrg@redhat.com>
* armcopro.c (write_cp15_reg): Set CHANGEMODE if endianness changes.
(read_cp15_reg): Make non-static.
(XScale_cp15_LDC): Update for write_cp15_reg() change.
(XScale_cp15_MCR): Likewise.
(XScale_cp15_write_reg): Likewise.
(XScale_check_memacc): New function. Check for breakpoints being
activated by memory accesses. Does not support the Branch Target
Buffer.
(XScale_set_fsr_far): New function. Set FSR and FAR for XScale.
(XScale_debug_moe): New function. Set the debug Method Of Entry,
if configured.
(write_cp14_reg): Reset count counter if requested.
* armdefs.h (struct ARMul_State): New members `LastTime' and
`CP14R0_CCD' used for the timer/counters.
(ARMul_CP13_R0_FIQ, ARMul_CP13_R0_IRQ, ARMul_CP13_R8_PMUS,
ARMul_CP14_R0_ENABLE, ARMul_CP14_R0_CLKRST, ARMul_CP14_R0_CCD,
ARMul_CP14_R0_INTEN0, ARMul_CP14_R0_INTEN1, ARMul_CP14_R0_INTEN2,
ARMul_CP14_R0_FLAG0, ARMul_CP14_R0_FLAG1, ARMul_CP14_R0_FLAG2,
ARMul_CP14_R10_MOE_IB, ARMul_CP14_R10_MOE_DB, ARMul_CP14_R10_MOE_BT,

ARMul_CP15_R5_ST_ALIGN, ARMul_CP15_R5_IMPRE, ARMul_CP15_R5_MMU_EXCPT,
ARMul_CP15_DBCON_M, ARMul_CP15_DBCON_E1, ARMul_CP15_DBCON_E0): New
defines for XScale registers.
(XScale_check_memacc, XScale_set_fsr_far, XScale_debug_moe): Prototype.
(ARMul_Emulate32, ARMul_Emulate26): Clean up function definition.
(ARMul_Emulate32): Handle the clock counter and hardware instruction
breakpoints. Call XScale_set_fsr_far() for software breakpoints and
software interrupts.
(LoadMult): Call XScale_set_fsr_far() for data aborts.
(LoadSMult): Likewise.
(StoreMult): Likewise.
(StoreSMult): Likewise.
* armemu.h (write_cp15_reg): Update prototype.
* arminit.c (ARMul_NewState): Initialise CP14R0_CCD and LastTime.
(ARMul_Abort): If XScale, check for FIQ and IRQ being enabled in CP13
register 0.
* armvirt.c (GetWord): Call XScale_check_memacc().
(PutWord): Likewise.
