From be19bd5cd0f454b63298844a0b5377e029b2caad Mon Sep 17 00:00:00 2001 From: Harald Welte Date: Wed, 19 Dec 2007 14:19:38 +0100 Subject: ARM: arm920/s3c24xx: IRQ demulitplexer callback This patch adds a IRQ demultiplexer callback to the arm920 cpu core code, plus a stub implementation of it for the S3C2410. The purpose is to allow arm920t implementations such as the s3c24x0 to implement interrupt handlers in u-boot without having to touch core arm920t code.
