Hello, I find there are some macros about loongson's CPU and SoC, $ vim barebox/arch/mips/Kconfig 174 config CPU_LOONGSON1B 175 bool "Loongson 1B" 176 depends on SYS_HAS_CPU_LOONGSON1B 177 select CPU_LOONGSON1 178 help 179 The Loongson 1B is a 32-bit SoC, which implements the MIPS32 180 release 2 instruction set. Here I want to list some Chips from this page: http://www.loongson.cn/product/ NAME CPU Core(s) The loongson 3, for series/server & desktop 3A3000/3B3000 GS464E 64bit x4 3A2000/3B2000 GS464E 64bit x4 3B1500 GS464 64bit x8 3A1000 GS464 64bit x4 The loongson 2, for series/low power 2K1000 GS264 64bit x2 2F GS464 64bit x1 2H GS464 64bit x1 The loongson 1, for series/embeded 1C101 GS132R 32bit ? 1D GS132 32bit ? 1C GS232 32bit x1 1B GS232 32bit x1 <-- loongson 1b 1A GS232 32bit x1 the CPU name of LOONGSON1B is socalled GS232, shall we change CPU_LOONGSON1 to CPU_GS232? here is a introduce for GS232 in Chinese: - - - - 龙芯 232 核是一款实现 MIPS32 兼容且支持 EJTAG 调试的双发射处理器，通过采用转移 预测、寄存器重命名、乱序发射、路预测的指令 CACHE、非阻塞的数据 CACHE、写合并收集 等技术来提高流水线的效率。 - - - - base on this description, is it compact with MIPS32. for loongson's other cores, shall we define some macro: CONFIG_CPU_GS232 CONFIG_CPU_GS264 CONFIG_CPU_GS464 Regards, duhuanpeng _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
