From 5f240718b475dcddee86b138b624f24c681dbb29 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Wed, 20 Jan 2010 15:23:54 +0900 Subject: sh: mach-sdk7786: Split out FPGA IRQ controller setup. This moves out the FPGA IRQ controller setup code to its own file, in preparation for switching off of IRL mode and having it provide its own irq_chip.
