Title:
  Integrator/CP regression after QOM'ification of integratorcp.c

Status in HelenOS branches:
  New
Status in QEMU:
  Fix Released

Bug description:
  The following command line no longer works (i.e. the guest does not
  boot) with QEMU 2.7.0:

  qemu-system-arm -M integratorcp -m 128M -kernel
  HelenOS-0.6.0-arm32-integratorcp.boot

  I did git bisect and came to this revision:

  hw/arm: QOM'ify integratorcp.c
  
  * Drop the use of old SysBus init function and use instance_init
  * Remove the empty 'icp_pic_class_init' from Typeinfo

  Upon closer inspection, I discovered that for some reason s->memsz in
  integratorcm_init() is zero. In the last good revision, this value was
  128. As a temporary workaround, hardcoding it to this expected value
  fixes the problem.

Turns out integratorcm_init() depends on the memsz property being
already set, but that unfortunately is not the case as setting of memsz
depends on integratorcm_init() having completed:

dev = qdev_create(NULL, TYPE_INTEGRATOR_CM);<= calls 
integratorcm_init(), needs memsz
qdev_prop_set_uint32(dev, "memsz", ram_size >> 20); <= memsz set here, 
needs dev
