From 092146ab09920ae0076a96e45bf04b4d7be22c0c Mon Sep 17 00:00:00 2001 From: Bharat Bhushan Date: Thu, 25 Jan 2018 10:28:53 +0000 Subject: [PATCH] virt/vgic: Increase number of DeviceIDs to 17 FSL-MC bus devices uses device-ids from 0x10000 to 0x20000. So to support MSI interrupts for mc-bus devices we need vgi-ITS device-id table of size 2^17 to support deviceid range from 0x10000 to 0x20000.
