Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20140417-1' into staging

target-arm queue:
 * AArch64 system mode support; this is all the CPU emulation code
   but not the virt board support
 * cadence_ttc match register bugfix
 * Allwinner A10 PIC, PIT and ethernet fixes
   [with update to avoid duplicate typedef]
 * zynq-slcr rewrite
 * cadence_gem bugfix
 * fix for SMLALD/SMLSLD insn in A32
 * fix for SQXTUN in A64
