From 613e09b46a86d454fb53f7e9eac5e240f1e3bacf Mon Sep 17 00:00:00 2001 From: Russell King Date: Tue, 30 Dec 2008 16:24:17 +0000 Subject: [ARM] footbridge: set dc21285 clock rate from command line Allow the footbridge clock rate to be specified on the kernel command line. This allows us to work-around broken Personal Server firmware.
