Peter Maydell b558e29521 hw/arm/fsl-imx6ul: Connect VIRQ and VFIQ
Connect the VIRQ and VFIQ lines from the GIC to the CPU;
these exist always for both CPU and GIC whether the
virtualization extensions are enabled or not, so we
can just unconditionally connect them.

Thomas Huth f8bf4b6d38 hw/arm/fsl-imx7: Fix introspection problems with the "fsl, imx7" device
Running QEMU with valgrind indicates a problem here:

 "'arguments':{'typename':'fsl,imx7'}}" \
 "{'execute': 'human-monitor-command', " \

Use the new sysbus_init_child_obj() and object_initialize_child() to make
sure that the objects are removed correctly when the parent gets destroyed.

Peter Maydell fc38a1120c Remove checks on MAX_SERIAL_PORTS that are just bounds checks
Remove checks on MAX_SERIAL_PORTS that were just checking whether
they were within bounds for the serial_hds[] array and falling
back to NULL if not. This isn't needed with the serial_hd()
function, which returns NULL for all indexes beyond what the
user set up.

Thomas Huth f640a5914f hw/arm/fsl-imx: Fix introspection problem with fsl-imx6 and fsl-imx7
QEMU currently exits unexpectedly when trying to introspect the fsl-imx6
and fsl-imx7 devices on systems with many SMP CPUs:

$ echo "{'execute':'qmp_capabilities'}"\
       "{'execute':'device-list-properties',"\
       " 'arguments':{'typename':'fsl,imx6'}}" \
       | arm-softmmu/qemu-system-arm -M virt,accel=qtest -qmp stdio -smp 8
{"QMP": {"version": {"qemu": {"micro": 91, "minor": 11, "major": 2},
 "package": "build-all"}, "capabilities": []}}
{"return": {}}
fsl,imx6: Only 4 CPUs are supported (8 requested)

And:

$ echo "{'execute':'qmp_capabilities'}"\
       "{'execute':'device-list-properties',"\
       " 'arguments':{'typename':'fsl,imx7'}}" \
       | arm-softmmu/qemu-system-arm -M raspi2,accel=qtest -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 91, "minor": 11, "major": 2},
 "package": "build-all"}, "capabilities": []}}
{"return": {}}
fsl,imx7: Only 2 CPUs are supported (4 requested)

This happens because these devices are doing an exit() from their
instance_init function - which should never be done since instance_init
can be called at any time for device introspection! Fix it by moving
the deadly check into the realize() function instead.

Andrey Smirnov 757282ada8 i.MX: Add i.MX7 SOC implementation.
The following interfaces are partially or fully emulated:

    * up to 2 Cortex A9 cores (SMP works with PSCI)
    * A7 MPCORE (identical to A15 MPCORE)
    * 4 GPTs modules
    * 7 GPIO controllers
    * 2 IOMUXC controllers
    * 1 CCM module
    * 1 SVNS module
    * 1 SRC module
    * 1 GPCv2 controller
    * 4 eCSPI controllers
    * 4 I2C controllers
    * 7 i.MX UART controllers
    * 2 FlexCAN controllers
    * 2 Ethernet controllers (FEC)
    * 3 SD controllers (USDHC)
    * 4 WDT modules
    * 1 SDMA module
    * 1 GPR module
    * 2 USBMISC modules
    * 2 ADC modules
    * 1 PCIe controller

Tested to boot and work with upstream Linux (4.13+) guest.
