[Stable-10.2.1 61/78] hw/arm/aspeed_ast27x0: Fix EHCI3/4 IRQ routing to GIC
Posted by Michael Tokarev 9 hours ago
From: Jamin Lin <jamin_lin@aspeedtech.com>

EHCI3 and EHCI4 were missing entries in aspeed_soc_ast2700a1_irqmap,
so their source IRQs were never routed through the INTC OR-gates.

As a result, EHCI3/4 interrupts were not propagated to the GIC,
causing incorrect interrupt behavior for these controllers.

Add EHCI3 and EHCI4 to the IRQ map and route them to the same INTC
group as other shared peripherals, ensuring their interrupts are
properly connected to the GIC.
