Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20160316-1' into staging

target-arm queue:
 * loader: Fix incorrect parameter name in load_image_mr()
 * Implement MRS (banked) and MSR (banked) instructions
 * virt: Implement versioning for machine model
 * i.MX: some initial patches preparing for i.MX6 support
 * new ASPEED AST2400 SoC and palmetto-bmc machine
 * bcm2835: add some more raspi2 devices
 * sd: fix segfault running "info qtree"
