From ab48ca1a661b9ab8e3fee9fe2df65432b09ed073 Mon Sep 17 00:00:00 2001 From: Srikanth Srinivasan Date: Wed, 10 Feb 2010 17:32:43 +0800 Subject: ppc/p4080: Fix synchronous frequency calculations When DDR is in synchronous mode, the existing code assigns sysclk frequency to DDR frequency. It should be synchronous with the platform frequency. CPU frequency is based on platform frequency in synchronous mode. Also fix: * Fixes the bit mask for DDR_SYNC (RCWSR5[184]) * Corrects the detection of synchronous mode.
