+From 2b3ca15058c974f2c20bd057a58a10c414b83fef Mon Sep 17 00:00:00 2001
+From: Lars-Peter Clausen <lars@metafoo.de>
+Date: Sat, 17 Jul 2010 11:07:51 +0000
+Subject: [PATCH] MIPS: JZ4740: Add base support for Ingenic JZ4740 System-on-a-Chip
+
+Adds a new cpu type for the JZ4740 to the Linux MIPS architecture code.
+It also adds the iomem addresses for the different components found on
+a JZ4740 SoC.
