From 1287e0c55a2ee2c575ac9ce8e4302cd4085be876 Mon Sep 17 00:00:00 2001 From: Wolfgang Grandegger Date: Thu, 5 Jun 2008 13:12:07 +0200 Subject: TQM8548: Basic support for the TQM8548 modules This patch adds basic support for the TQM8548 module from TQ-Components (http://www.tqc.de/) including DDR2 SDRAM initialisation and support for eTSEC 3 and 4 Furthermore Flash buffer write has been enabled to speed up output to the Flash by approx. a factor of 10.
