2012-04-27target-arm: Move A9 config_base_address reset value to ARMCPUPeter Maydell
Move the A9 config_base_address cp15 register reset value to ARMCPU. This should become a QOM property so that the Highbank board can set it without having to pull in cpu-qom.h, but at least this avoids the implicit dependency on reset ordering that the previous workaround had.

2012-04-27target-arm: Change cpu_arm_init() return type to ARMCPUAndreas Färber
Make cpu_arm_init() return a QOM ARMCPU, so that we don't need to obtain an ARMCPU through arm_env_get_cpu() in machine init code. This requires to adjust the inclusion site of cpu-qom.h and in turn, forward-looking, to homogenize its include order. cpu_init() must still return a CPUARMState for backwards and cross-target compatibility, so adjust the cpu_init macro.

2012-04-21target-arm: Move reset handling to arm_cpu_resetPeter Maydell
Now that cpu_reset_model_id() has gone we can move the reset code over to the class reset function and have cpu_state_reset simply do a reset on the CPU QOM object. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Acked-by: Andreas Färber <afaerber@suse.de>
2012-04-21target-arm: Move cache ID register setup to cpu specific init fnsPeter Maydell
Move cache ID register reset out of cpu_reset_model_id() by creating a field for the reset value in ARMCPU and setting it up in the cpu specific init functions. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Acked-by: Andreas Färber <afaerber@suse.de>
2012-04-21target-arm: Move feature register setup to per-CPU init fnsPeter Maydell
Move feature register value setup to per-CPU init functions. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Acked-by: Andreas Färber <afaerber@suse.de>
2012-04-21target-arm: Move SCTLR reset value setup to per cpu init fnsPeter Maydell
Move the reset value of SCTLR to ARMCPU, initialised in the per-cpu init functions. It can then be reset by a simple copy, and we can drop the code from cpu_reset_model_id(). Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Acked-by: Andreas Färber <afaerber@suse.de>
2012-04-21target-arm: Move CTR setup to per cpu init fnsPeter Maydell
Move CTR (cache type register) value to an ARMCPU field set up by per-cpu init fns. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Acked-by: Andreas Färber <afaerber@suse.de>
2012-04-21target-arm: Move MVFR* setup to per cpu init fnsPeter Maydell
Move the MVFR* VFP feature register values to ARMCPU, so they are set up by the implementation-specific instance init functions rather than in cpu_reset_model_id(). Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Acked-by: Andreas Färber <afaerber@suse.de>
2012-04-21target-arm: Move FPSID config to cpu init fnsPeter Maydell
Move the reset FPSID to the ARMCPU struct, and set it in the per-implementation instance init function. At reset we then just copy the reset value into the CPUARMState field. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Acked-by: Andreas Färber <afaerber@suse.de>
2012-04-21target-arm: Move feature bit settings to CPU init fnsPeter Maydell
Move the setting of the feature bits from cpu_reset_model_id() to each CPU's instance init function. This requires us to move the features field in CPUARMState so that it is not cleared on reset. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Acked-by: Andreas Färber <afaerber@suse.de>
2012-04-21target-arm: Add QOM subclasses for each ARM cpu implementationPeter Maydell
Register subclasses for each ARM CPU implementation. Let arm_cpu_list() enumerate CPU subclasses in alphabetical order, except for special value "any". Replace cpu_arm_find_by_name()'s string -> CPUID lookup by storing the CPUID (aka MIDR, Main ID Register) value in the class.

2012-03-29target-arm: Minimalistic CPU QOM'ificationAndreas Färber
Introduce only one non-abstract type TYPE_ARM_CPU and do not touch cp15 registers to not interfere with Peter's ongoing remodelling. Embed CPUARMState as first (additional) field of ARMCPU. Let CPUClass::reset() call cpu_state_reset() for now. Signed-off-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
