Can someone please point me to the documentation where I can find the definition for GICD_IROUTERn register. I see it mentioned in DDI0516B_gic5000_r0p0_trm but not the complete definition.

I'm not able to disable the affinity routing (i.e. ARE_S and ARE_NS bits being set always). Reset value of GICD_CTLR register is 0x30.

Actually I want to forward the interrupt from Distributor to multiple Cores but seems to use ITARGETSR, affinity…
