Merge remote-tracking branch 'bonzini/hw-dirs' into staging
* bonzini/hw-dirs:
sh: move files referencing CPU to hw/sh4/
ppc: move more files to hw/ppc
ppc: move files referencing CPU to hw/ppc/
m68k: move files referencing CPU to hw/m68k/
i386: move files referencing CPU to hw/i386/
arm: move files referencing CPU to hw/arm/
hw: move boards and other isolated files to hw/ARCH
ppc: express FDT dependency of pSeries and e500 boards via default-configs/
build: always link device_tree.o into emulators if libfdt available
hw: include hw header files with full paths
ppc: do not use ../ in include files
vt82c686: vt82c686 is not a PCI host bridge
virtio-9p: remove PCI dependencies from hw/9pfs/
virtio-9p: use CONFIG_VIRTFS, not CONFIG_LINUX
hw: move device-hotplug.o to toplevel, compile it once
hw: move qdev-monitor.o to toplevel directory
hw: move fifo.[ch] to libqemuutil
hw: move char backends to backends/
Conflicts:
