IRQ_OFFSET

Title: IRQ_OFFSET

 Hi all,

The macro IRQ_OFFSET is used to map interrupt vector(IRQ) to its interrupt sources.
 How the value of IRQ_OFFSET is decided?  Is there any standard way to define the value of IRQ_OFFSET?

Note: The IRQ_OFFSET is chosen so that the device interrupt don't overlap with the processor exceptions.

 What else should we take into consideration while deciding the value of  IRQ_OFFSET?

Thanks,
Saumendra
