From: Wu Zhangjin Date: Thu, 2 Jul 2009 15:26:08 +0000 (+0800) Subject: MIPS: Loongson: Change naming methods X-Git-Tag: v2.6.32-rc1~658^2~26 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8e4971175acc910eb4258df82a6bd8f2c4e4e5b5;p=profile%2Fcommon%2Fkernel-common.git MIPS: Loongson: Change naming methods To make source code of loongson sharable to the machines(such as gdium) made by the other companies, we rename arch/mips/lemote to arch/mips/loongson, asm/mach-lemote to asm/mach-loongson, and rename lm2e to the name of the machine: fuloong-2e. accordingly, FULONG are renamed to FULOONG2E to make it distinguishable to the future FULOONG2F. and also, some other relative tuning is needed.
