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.
