From b3a1bde4db9889feb116330bff21214811c940e4 Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Wed, 14 Feb 2007 19:14:56 +0100 Subject: [ARM] 4108/2: Allow multiple GIC interrupt controllers in a system The current implementation only assumes one GIC to be present in the system. However, there are platforms with more than one cascaded interrupt controllers (RealView/EB MPCore for example).

This patch enables revC by default and adds a config option for building the kernel for the revB platform. Since the SCU base address was hard-coded in the proc-v6.S file (and only valid for RealView/EB revB), this patch also adds a more generic support for defining the SCU information.
