From 55045ff5557bc804752e84dca5d1b1f1d4bb4e31 Mon Sep 17 00:00:00 2001 From: Wu Zhangjin Date: Wed, 11 Nov 2009 13:39:12 +0800 Subject: [PATCH] MIPS: Loongson 2F: Cleanup the #if clauses This patch adds two new kernel options: CPU_SUPPORTS_CPUFREQ and CPU_SUPPORTS_ADDRWINCFG to describe the new features of Loongons 2F and replaces the several ugly #if clauses by them. These two options will be utilized by the future loongson revisions and related drivers such as the coming Loongson 2F CPUFreq driver.
