From 30ad29bb48881ee11f5daf30c6fc50292ae08c57 Mon Sep 17 00:00:00 2001 From: Huacai Chen Date: Tue, 21 Apr 2015 10:00:35 +0800 Subject: MIPS: Loongson: Naming style cleanup and rework Currently, code of Loongson-2/3 is under loongson directory and code of Loongson-1 is under loongson1 directory. Besides, there are Kconfig options such as MACH_LOONGSON and MACH_LOONGSON1. This naming style is very ugly and confusing. Since Loongson-2/3 are both 64-bit general- purpose CPU while Loongson-1 is 32-bit SoC, we rename both file names and Kconfig symbols from loongson/loongson1 to loongson64/loongson32.
