这个内核配置文件，要经过config进行处理
第一行表示，要包含一个文件
include "arch/evbmips/conf/std.loongson"， 内容如下：
# $NetBSD: std.loongson,v 1.2 2017/08/08 12:22:21 maya Exp $ machine evbmips mips include "conf/std" # MI standard options options MIPS3_ENABLE_CLOCK_INTR options ENABLE_MIPS_16KB_PAGE options PMON # Platform support options MIPS3_LOONGSON2 options MIPS3 options MIPS3_LOONGSON2F options LOONGSON2 # IDT LOONGSON2 makeoptions LP64="yes" options EXEC_ELF64 options EXEC_ELF32 # exec ELF32 binaries options EXEC_SCRIPT # exec #! scripts options COMPAT_NETBSD32 makeoptions CPUFLAGS="-mips3 -mdivide-breaks -Wa,-mfix-loongson2f-btb -Wa,-mfix-loongson2f-jump -Wa,-mfix-loongson2f-nop" # CPU codegen options makeoptions DEFTEXTADDR="0x80200000" makeoptions BOARDTYPE="loongson" include "arch/evbmips/conf/files.loongson"
它又包含了两个文件：
1 conf/std
