From b2b3dc2fc41ef441610d0140f0f5ccacbd43f40c Mon Sep 17 00:00:00 2001 From: Ronen Shitrit Date: Mon, 15 Sep 2008 10:40:35 +0300 Subject: [ARM] Kirkwood: add support for newer SoC models Add support to the Kirkwood port for newer device models and silicon revisions. Instead of looking at the DEVICE_ID register, the device version is now determined by looking at the PCI-Express device ID and revision registers, as it is done for orion5x, and this information is used to determine the TCLK frequency, again, as it is done for orion5x.
