| C-SKY Multi-processors Interrupt Controller |
| =========================================== |
| |
| C-SKY Multi-processors Interrupt Controller is designed for ck807/ck810/ck860 |
| SMP soc, and it also could be used in non-SMP system. |
| |
| Interrupt number definition: |
| |
| 0-15 : software irq, and we use 15 as our IPI_IRQ. |
| 16-31 : private irq, and we use 16 as the co-processor timer. |
| 31-1024: common irq for soc ip. |
