From 85749d24bcf90440b10394312e5b1c96d1a62cdb Mon Sep 17 00:00:00 2001 From: Wu Zhangjin Date: Thu, 2 Jul 2009 23:26:45 +0800 Subject: MIPS: Loongson: Split common loongson source code out To share common loongson source code between all of the loongson-based machines. there is a need to split it out of the fuloong-2e/ directory. at the same time, other according tuning is needed. the machine-specific parts are defined as macros in relative header file, pci.h, mem.h, machine.h.
