This patch series attempts to bring the v7M code up to something resembling modern practice for QEMU devices: * proper QOM object for the armv7m "container" which holds the CPU, NVIC, etc cpu-internal devices" * split the systick out into its own device * use memory region links rather than having the NVIC and bitband map themselves directly into the system memory space * have stm32f205 create the armv7m container via the QOM APIs rather than armv7m_init(), since that fits better with the rest of that SoC's code
These patches sit on top of the NVIC rewrite patchset; you can find a git branch with the whole lot at: https://git.linaro.org/people/peter.maydell/qemu-arm.git v7m-qomify thanks -- PMM Peter Maydell (11): armv7m: Abstract out the "load kernel" code armv7m: Move NVICState struct definition into header armv7m: QOMify the armv7m container armv7m: Use QOMified armv7m object in armv7m_init() armv7m: Make ARMv7M object take memory region link armv7m: Make NVIC expose a memory region rather than mapping itself armv7m: Make bitband device take the address space to access armv7m: Don't put core v7M devices under CONFIG_STELLARIS armv7m: Split systick out from NVIC stm32f205: Create armv7m object without using armv7m_init() stm32f205: Rename 'nvic' local to 'armv7m' hw/intc/Makefile.objs | 2 +- hw/timer/Makefile.objs | 1 + include/hw/arm/arm.h | 12 ++ include/hw/arm/armv7m.h | 63 +++++++ include/hw/arm/armv7m_nvic.h | 62 +++++++ include/hw/arm/stm32f205_soc.h | 4 +- include/hw/timer/armv7m_systick.h | 34 ++++ hw/arm/armv7m.c | 380 +++++++++++++++++++++++++------------- hw/arm/netduino2.c | 7 +- hw/arm/stm32f205_soc.c | 28 ++- hw/intc/armv7m_nvic.c | 214 ++++----------------- hw/timer/armv7m_systick.c | 239 ++++++++++++++++++++++++ default-configs/arm-softmmu.mak | 2 + hw/timer/trace-events | 6 + 14 files changed, 733 insertions(+), 321 deletions(-) create mode 100644 include/hw/arm/armv7m.h create mode 100644 include/hw/arm/armv7m_nvic.h create mode 100644 include/hw/timer/armv7m_systick.h create mode 100644 hw/timer/armv7m_systick.c -- 2.7.4
