From 3eab8095ef1658f5cd4927a0224b1214329cb348 Mon Sep 17 00:00:00 2001 From: Manuel Lauss Date: Thu, 8 Dec 2011 10:42:16 +0000 Subject: [PATCH] MIPS: Alchemy: merge Au1000 and Au1300-style IRQ controller code. With a generic plat_irq_dispatch (for Alchemy at least) code for both interrupt controller types can coexist in a single kernel image and be autodetected at runtime.
