Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20180309' into staging

target-arm queue:
 * i.MX: Add i.MX7 SOC implementation and i.MX7 Sabre board
 * Report the correct core count in A53 L2CTLR on the ZynqMP board
 * linux-user: preliminary SVE support work (signal handling)
 * hw/arm/boot: fix memory leak in case of error loading ELF file
 * hw/arm/boot: avoid reading off end of buffer if passed very
   small image file
 * hw/arm: Use more CONFIG switches for the object files
 * target/arm: Add "-cpu max" support
 * hw/arm/virt: Support -machine gic-version=max
 * hw/sd: improve debug tracing
 * hw/sd: sdcard: Add the Tuning Command (CMD 19)
 * MAINTAINERS: add Philippe as odd-fixes maintainer for SD

  target/arm: Query host CPU features on-demand at instance init
  arm: avoid heap-buffer-overflow in load_aarch64_image
  arm: fix load ELF error leak
  hw/arm: Use more CONFIG switches for the object files
  aarch64-linux-user: Add support for SVE signal frame records
  aarch64-linux-user: Add support for EXTRA signal frame records
