I recently added the support for CPU1 to the xilinx-zynq-a9 machine
(hw/arm/xilinx_zynq.c). However, the reset behaviour doesn't match exactly with
the hardware. After a system reset (SRST), the CPU1 should execute a wfe
instruction and then load the start address from 0xfffffff0:

  hw/arm/boot: Use hooks if PSCI is disabled
  hw/arm/xilinx_zynq: Add CPU1 reset
