+title: Aspeed Coprocessor Vectored Interrupt Controller
+
+maintainers:
+  - Andrew Jeffery <andrew@codeconstruct.com.au>
+
+description:
+  The Aspeed AST2400 and AST2500 SoCs have a controller that provides interrupts
+  to the ColdFire coprocessor. It's not a normal interrupt controller and it
+  would be rather inconvenient to create an interrupt tree for it, as it
+  somewhat shares some of the same sources as the main ARM interrupt controller
+  but with different numbers.
+
+  The AST2500 also supports a software generated interrupt.
