[Qemu-devel] [PATCH v2 4/5] target/arm: Restrict R and M profiles to TCG

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

KVM is only able to run on CPUs based on the A-Profile architecture.

The following CPUs are disabled:

* M-Profile Architecture

  - Cortex-M3
  - Cortex-M4
  - Cortex-M33

* R-Profile Architecture

  - Cortex-R5
  - Cortex-R5F
