[Qemu-devel] [PATCH 0/6] ARM: MPU support for Cortex-M3/M4 emulation

[Alex Zuepke]

This patch series enables MPU support for Cortex-M3/M4 devices,
based on the existing MPU support for Cortex-R series in QEMU.
The MPU supports a variable number of windows and default to 8, the current
limit on most Cortex-M3/M4 devices. Also, the necessary registers for
exception handling and fault decoding are implemented.
Like on Cortex-R5, the MPU can be turned off by setting "pmsav7-dregion" to
zero.

Alex Zuepke (6):
  ARM: add Cortex-M3/M4 exception configuration and status registers
  ARM: accessors to Cortex-M3/M4 exception configuration and status
    registers
  ARM: Cortex-M3/M4: honor STKALIGN in CCR
  ARM: Cortex-M3/M4: on exception, set basic bits in exhandling
    registers
  ARM: enable ARM_FEATURE_MPU for Cortex-M3/M4
  ARM: enable PMSAv7-style MPU on Cortex-M3/M4
