[Qemu-arm] [PATCH v2 0/3] arm: add skeleton Cortex M0 CPU model

[Stefan Hajnoczi]

v2:
 * Share code between ARMv6-M and ARMv7-M [Peter]

This patch series adds a skeleton ARM Cortex M0 CPU model and an ARMv6M object
so that machine types can make use of it.

These patches cannot be merged until Julia Suvorova's Cortex M0 work is
complete, since the target/arm/ code does not implement ARMv6-M behavior
faithfully yet.

The micro:bit emulation will be the first machine type to make use of ARMv6-M.

Stefan Hajnoczi (3):
  hw/arm: extract ARM M Profile base class from ARMv7-M
  hw/arm: add ARMv6M object
  target/arm: add "cortex-m0" CPU model
