From c28d3bbe963f4c57937d6fdc1dd63cd3562c147c Mon Sep 17 00:00:00 2001 From: Wolfgang Grandegger Date: Fri, 23 Oct 2009 12:03:13 +0200 Subject: video: mb862xx: improve board-specific Lime configuration To avoid board-specific code accessing the mb862xx registers directly, the public function mb862xx_probe() has been introduced. Furthermore, the "Change of Clock Frequency" and "Set Memory I/F Mode" registers are now defined by CONFIG_SYS_MB862xx_CCF and CONFIG_SYS_MB862xx__MMR, respectively. The BSPs for the socrates and lwmon5 boards have been adapted accordingly.
