MPC86xx processors are based on the e600 core, which is not the case in qemu where it is based on the 7400 processor.
This patch creates the e600 core and instantiates the MPC86xx processors based on it. Therefore, adding the high BATs and the SPRG 4..7 registers, which are e600-specific [1]. This allows to define the MPC8610 processor too and my program running on a real MPC8610 target is now able to run on qemu :) [1] http://cache.freescale.com/files/32bit/doc/ref_manual/E600CORERM.pdf Signed-off-by: Julio Guerra <gu...@julio.in> --- target-ppc/cpu-models.c | 10 ++-- target-ppc/cpu-models.h | 4 +- target-ppc/translate_init.c | 122 ++++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 127 insertions(+), 9 deletions(-) diff --git a/target-ppc/cpu-models.c b/target-ppc/cpu-models.c index 17f56b7..8a2ab50 100644 --- a/target-ppc/cpu-models.c +++ b/target-ppc/cpu-models.c @@ -792,17 +792,15 @@ POWERPC_DEF_SVR("MPC8572E", "MPC8572E", CPU_POWERPC_MPC8572E, POWERPC_SVR_8572E, e500v2) /* e600 family */ - POWERPC_DEF("e600", CPU_POWERPC_e600, 7400, + POWERPC_DEF("e600", CPU_POWERPC_e600, e600, "PowerPC e600 core") /* PowerPC e600 microcontrollers */ -#if defined(TODO) POWERPC_DEF_SVR("MPC8610", "MPC8610", - CPU_POWERPC_MPC8610, POWERPC_SVR_8610, 7400) -#endif + CPU_POWERPC_MPC8610, POWERPC_SVR_8610, e600) POWERPC_DEF_SVR("MPC8641", "MPC8641", - CPU_POWERPC_MPC8641, POWERPC_SVR_8641, 7400) + CPU_POWERPC_MPC8641, POWERPC_SVR_8641, e600) POWERPC_DEF_SVR("MPC8641D", "MPC8641D", - CPU_POWERPC_MPC8641D, POWERPC_SVR_8641D, 7400) + CPU_POWERPC_MPC8641D, POWERPC_SVR_8641D, e600) /* 32 bits "classic" PowerPC */ /* PowerPC 6xx family */ POWERPC_DEF("601_v0", CPU_POWERPC_601_v0, 601, diff --git a/target-ppc/cpu-models.h b/target-ppc/cpu-models.h index a94f835..8ba96bb 100644 --- a/target-ppc/cpu-models.h +++ b/target-ppc/cpu-models.h @@ -731,9 +731,7 @@ enum { POWERPC_SVR_8568E = 0x807D0011 | POWERPC_SVR_E500, POWERPC_SVR_8572 = 0x80E00010 | POWERPC_SVR_E500, POWERPC_SVR_8572E = 0x80E80010 | POWERPC_SVR_E500, -#if 0 - POWERPC_SVR_8610 = xxx, -#endif + POWERPC_SVR_8610 = 0x80A00011, POWERPC_SVR_8641 = 0x80900021, POWERPC_SVR_8641D = 0x80900121, };
