| 4 | Subject: [PATCH] virt/vgic: Increase number of DeviceIDs to 17 |
| 5 | |
| 6 | FSL-MC bus devices uses device-ids from 0x10000 to 0x20000. |
| 7 | So to support MSI interrupts for mc-bus devices we need |
| 8 | vgi-ITS device-id table of size 2^17 to support deviceid |
| 9 | range from 0x10000 to 0x20000. |
