[Qemu-devel] [PATCH v1 0/4] Improve ARMv7-M architecture emulation

[Meador Inge <meadori@codesourcery.com>]

Hi All,

This patch series is an attempt to improve the current ARMv7-M support
by making it easier to run applications that only require architecture
level support from the emulation (basically an ISS).  We are mostly there
already, but there are some cases that we don't handle well.  For example,
running an ARMv7-M application that uses SVC with only '-cpu cortex-m3'
currently will not work because the NVIC is not initialized (the Cortex-M3
gets wedged into the default Integrator/CP board, hence PATCH 3).

The first patch fixes support for using -kernel with ARMv7-M applications.
The second patch fixes the SYS_HEAPINFO semihosting call to work for ARMv7-M
applications.  The third patch allows for the default machine to be chosen
depending on what -cpu is specified.  The final patch adds support for a
"dummy" ARMv7-M board so that QEMU can be used as an ISS for ARMv7-M
applications.

Meador Inge (4):
  hw: Add support for loading ARMv7-M applications via -kernel
  target-arm: Make SYS_HEAPINFO work for ARMv7-M
  hw: Deduce the default machine from the specified CPU model
  hw: Add support for a dummy ARMv7-M board
