From f3a329acb26017d8e10e9c93e1e726c2a5ac634a Mon Sep 17 00:00:00 2001 From: Martin Krause Date: Mon, 25 Feb 2008 13:27:52 +0100 Subject: TQM5200: fix bug in SDRAM initialization code This patch fixes a bug in the SDRAM initialization code for the TQM5200. The hi_addr bit is now set correctly. Without this patch the hi_addr bit is always set to 1, if the second SDRAM bank is not populated. For other MPC5200 boards a correspondig patch has already been applied some time ago, see commit a63109281ad41b0fb489fdcb901171f76bcdbc2c.
