Peter Maydell authoredThe GICv3 specification says that the GICD_TYPER.SecurityExtn bit is RAZ if GICD_CTLR.DS is 1. We were incorrectly making it RAZ if the security extension is unsupported. "Security extension unsupported" always implies GICD_CTLR.DS == 1, but the guest can also set DS on a GIC which does support the security extension. Fix the condition to correctly check the GICD_CTLR.DS bit. Signed-off-by:
