arm: Wire up GICv2 virt support on A15/A7 boards

[Qemu-devel] [PATCH 6/9] hw/arm/fsl-imx6ul: Connect VIRQ and VFIQ

Posted by Peter Maydell 7 years, 2 months ago

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.
