From 158557001afe167dcb848bb14ba0f2f20aeb25a1 Mon Sep 17 00:00:00 2001 From: Sudhakar Rajashekhara Date: Tue, 8 Jun 2010 11:01:58 +0530 Subject: TI: DaVinci: Prepare for da850 support DA850/OMAP-L138 is a new SoC from Texas Instruments (http://focus.ti.com/docs/prod/folders/print/omap-l138.html). This SoC is similar to DA830/OMAP-L137 in many aspects. Hence rename the da830 specific files and folders to da8xx to accommodate DA850/OMAP-L138.
