+ This interrupt controller is found in the Loongson-3 family of chips and
+ Loongson-2K series chips, as the primary package interrupt controller which
+ can route local I/O interrupt to interrupt lines of cores.
+ Be aware of the following points.
+ 1.The Loongson-2K0500 is a single core CPU;
+ 2.The Loongson-2K0500/2K1000 has 64 device interrupt sources as inputs, so we
+ need to define two nodes in dts{i} to describe the "0-31" and "32-61" interrupt
+ sources respectively.
