In this series we implement the COMPARE registers of the
SYS_timer, since they are used by Linux.

This fixes the hang reported by Niek here:
https://www.mail-archive.com/qemu-devel@nongnu.org/msg682090.html

Since v2:
- Fixed issue in COMPARE register reported by Luc

Since v1:
- Extracted unrelated patches to previous series
  (which happened to be mis-rebased)

Philippe Mathieu-Daudé (4):
  hw/timer/bcm2835: Introduce BCM2835_SYSTIMER_COUNT definition
  hw/timer/bcm2835: Rename variable holding CTRL_STATUS register
  hw/timer/bcm2835: Support the timer COMPARE registers
  hw/arm/bcm2835_peripherals: Correctly wire the SYS_timer IRQs
