[Qemu-devel] [PATCH v2 00/11] PPC: e5500 emulation

[Alexander Graf]

This patch set adds support to emulate an e5500 based virtual machine. We don't
have a machine model for that one yet, but with this patch set applied we can
fake the compatibility property of the MPC8544DS model into P5020DS, which
gets guest kernels working for me.

The patch set is based on my recent dynamic device tree work. For a ready to use
git tree, please check here:

  git://repo.or.cz/qemu/agraf.git ppc-e5500

To use the code, grab yourself an e5500 kernel and run:

  $ qemu-system-ppc64 -M mpc8544ds -cpu e5500 -nographic -kernel uImage \
    -machine dt_compatible=fsl,,P5020DS

This should get you a working kernel. Everything after that works just the same
as with e500v2 or e500mc.

v1 -> v2:

  - remove reset msr vector
  - clean up ivpr_mask code
  - make MAS2 64bit aware
