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.
