[Qemu-devel] [PATCH 0/7] PPC: Add FSL (e500) MMU emulation v5

[Alexander Graf]

In a global effort to get rid of KVM-only targets, this is the next
important piece of the puzzle: e500 emulation :).

We had support for running an e500 KVM guest for a while now, but the
code could not be tested without a real e500 machine, because it required
KVM to work. This patchset adds emulation for the e500 MMU, enabling
anyone to use the MPC8544DS emulation.

v1 -> v2:

  - fix linux-user build
  - optimize tlb invalidate & search

v2 -> v3:

  - add qdev patch (enables -drive if=virtio)
  - fix mpc initial tlb size comment
  - enable cpu reset

v3 -> v4:

  - remove tlb_nbs
  - rename BOOKE_FSL to BOOKE206
  - generalize implementation to be extensible for future MMUs
  - check if tsize should be set
  - check if iprot should be set
  - set RPN on tlb miss
  - implement tlb_invalidate_all
  - use specific helper to set PIDs
  - create generic booke206 tlb flushing function
  - drop base_addr
  - new patch: MPC7544DS: Use new TLB helper function

v4 -> v5:

  - dont check iprot during tlb flush on reset (scott)
  - model qdev conversion similar to versatilepb (pbrook)

Alexander Graf (7):
