From 5bc95aa2461f3b9f70ecbb2a9ec22f939fc33d6d Mon Sep 17 00:00:00 2001 From: Dmitry Eremin-Solenikov Date: Tue, 19 Apr 2011 18:56:45 +0400 Subject: Implement basic part of SA-1110/SA-1100 Basic implementation of DEC/Intel SA-1100/SA-1110 chips emulation. Implemented: - IRQs - GPIO - PPC - RTC - UARTs (no IrDA/etc.) - OST reused from pxa25x Everything else is TODO (esp. PM/idle/sleep!) - see the todo in the hw/strongarm.c Signed-off-by: Dmitry Eremin-Solenikov Signed-off-by: Aurelien Jarno --- target-arm/helper.c | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'target-arm/helper.c') diff --git a/target-arm/helper.c b/target-arm/helper.c index 12127dee74..bf843353e0 100644 --- a/target-arm/helper.c +++ b/target-arm/helper.c @@ -214,6 +214,11 @@ static void cpu_reset_model_id(CPUARMState *env, uint32_t id) env->cp15.c0_cachetype = 0xd172172; env->cp15.c1_sys = 0x00000078; break; + case ARM_CPUID_SA1100: + case ARM_CPUID_SA1110: + set_feature(env, ARM_FEATURE_STRONGARM); + env->cp15.c1_sys = 0x00000070; + break; default: cpu_abort(env, "Bad CPU ID: %x\n", id); break; @@ -378,6 +383,8 @@ static const struct arm_cpu_t arm_cpu_names[] = { { ARM_CPUID_CORTEXA9, "cortex-a9"}, { ARM_CPUID_TI925T, "ti925t" }, { ARM_CPUID_PXA250, "pxa250" }, + { ARM_CPUID_SA1100, "sa1100" }, + { ARM_CPUID_SA1110, "sa1110" }, { ARM_CPUID_PXA255, "pxa255" }, { ARM_CPUID_PXA260, "pxa260" }, { ARM_CPUID_PXA261, "pxa261" }, @@ -1553,6 +1560,8 @@ void HELPER(set_cp15)(CPUState *env, uint32_t insn, uint32_t val) case 9: if (arm_feature(env, ARM_FEATURE_OMAPCP)) break; + if (arm_feature(env, ARM_FEATURE_STRONGARM)) + break; /* Ignore ReadBuffer access */ switch (crm) { case 0: /* Cache lockdown. */ switch (op1) { -- cgit v1.2.3-55-g7522
