[Qemu-devel] [PATCH 00/11] ARMv7M: QOMify

From: Peter Maydell
Subject: [Qemu-devel] [PATCH 00/11] ARMv7M: QOMify
Date: Mon, 20 Feb 2017 15:35:54 +0000

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:

-- 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'
