Merge branch 'ppc-next' of git://repo.or.cz/qemu/agraf
* 'ppc-next' of git://repo.or.cz/qemu/agraf: PPC: move TLBs to their own arrays PPC: 440: Use 440 style MMU as default, so Qemu knows the MMU type PPC: E500: Use MAS registers instead of internal TLB representation PPC: Only set lower 32bits with mtmsr PPC: update openbios firmware PPC: mpc8544ds: Add hypervisor node PPC: calculate kernel,initrd,cmdline locations dynamically target-ppc: Handle memory-forced I/O controller access PPC: E500: Implement reboot controller
