* MIPS: Loongson-3: Fix build error after ld-version.sh modificationHuacai Chen2016-05-091-1/+1
| | | | | | | | | | | | | | | | | Commit d5ece1cb074b2c ("Fix ld-version.sh to handle large 3rd version part") modifies the ld version description. This causes a build error on Loongson-3, so fix it.

* MIPS: Loongson-3: Improve -march option and move it to PlatformHuacai Chen2016-01-221-0/+21
| | | | | | | | | | | | | | | | If GCC >= 4.9 and Binutils >=2.25, we use -march=loongson3a, otherwise we use -march=mips64r2, this can slightly improve performance. Besides, arch/mips/loongson64/Platform is a better location rather than arch/ mips/Makefile. Signed-off-by: Huacai Chen <chenhc@lemote.com> Cc: Aurelien Jarno <aurelien@aurel32.net> Cc: Steven J.

* MIPS: Loongson: Naming style cleanup and reworkHuacai Chen2015-06-211-0/+33
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.
