From ebdb5ab81c6b9fda130975d50fd6f43cb15c4ce6 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Mon, 6 Jul 2009 14:57:48 +0100 Subject: ARM: S3C64XX: Provide for board-specific IRQs Set up some IRQ space to allocation to off-SoC interrupt controllers. Default this to 16 IRQs. If individual boards require more than this then they will need to modify this file so allocating a small number helps reduce the number of modifications required.
