Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20140912' into staging

target-arm:
 * add "linux,stdout-path" to the virt DTB
 * fix a long standing bug with IRQ disabling on Cortex-M CPUs
 * implement input interrupt logic in the PL061
 * fix failure to load correct SP/PC on reset of Cortex-M CPUs
   if the vector table is not in a ROM-blob-in-RAM
 * provide flash devices for boot ROMs in the virt board
 * implement architectural watchpoints
 * fix misimplementation of Inner Shareable TLB operations that
   caused instability of guests in TCG SMP configurations
 * configure PL011 and PL031 in the virt board correctly with
   level-triggered interrupts rather than edge-triggered
 * support providing a device tree blob to ROM (firmware)
   images as well as to kernels
