[Qemu-devel] [PATCH v1 4/4] hw: Add support for a dummy ARMv7-M board |
Date: |
Mon, 27 Aug 2012 15:37:48 -0500 |
This patch adds support for a "dummy" ARMv7-M board so that
QEMU can be used as an ISS for ARMv7-M processors. For example,
running an image compiled for the Cortex-M3 with -cpu cortex-m3
should just work.
