Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20191015' into...

target-arm queue:
 * Add Aspeed AST2600 SoC support (but no new board model yet)
 * aspeed/wdt: Check correct register for clock source
 * bcm2835: code cleanups, better logging, trace events
 * implement v2.0 of the Arm semihosting specification
 * provide new 'transaction-based' ptimer API and use it
   for the Arm devices that use ptimers
 * ARM: KVM: support more than 256 CPUs
