WebProvides the interrupt number of the highest priority interrupt pending. A read of this register acts as an acknowledge for the interrupt. The read returns a spurious interrupt number of 1023 if any of the following apply: Forwarding of interrupts by the Distributor to the CPU interface is disabled.

WebTo fix this problem, implement a workaround that ensures read accesses to the GICD_In{E} registers are directed to the chip that owns the SPI, and disable GICv4.x features. To simplify code changes, the gic_configure_irq() function uses the same alias region for both read and write operations to GICD_ICFGR.
