From bafa9193d00c7bfff4c4aea0d48cd2b55a6378c2 Mon Sep 17 00:00:00 2001 From: Julien Grall Date: Mon, 11 Apr 2016 16:32:53 +0100 Subject: irqchip/gic-v2: Gather ACPI specific data in a single structure The ACPI code requires to use global variables in order to collect information from the tables. For now, a single global variable is used, but more will be added in a subsequent patch. To make clear they are ACPI specific, gather all the information in a single structure.

It means code duplication and make more tedious to add the support for another firmware table (like ACPI). Introduce a new structure and set of helpers to get/set the virtual GIC information. Also fill up the structure for GICv2.
