From 4b7171ac564786247a49eedc59d3060bddf2377c Mon Sep 17 00:00:00 2001 From: Eric Auger Date: Tue, 20 Dec 2016 09:20:00 +0100 Subject: arm/arm64: vgic: turn vgic_find_mmio_region into public We plan to use vgic_find_mmio_region in vgic-its.c so let's turn it into a public function. Also let's take the opportunity to rename the region parameter into regions to emphasize this latter is an array of regions.
