MIPS: Expand help text to list generic defconfigs

amalon · amalon · commit cccd0b9a72d2 · 2018-03-05T15:11:42.000Z
Expand the MIPS Makefile help text to list generic board names, generic defconfigs, and legacy defconfigs which have been converted to generic and are still usable. Here's a snippet of the new "make ARCH=mips help" output: ... If you are targeting a system supported by generic kernels you may configure the kernel for a given architecture target like so: {micro32,32,64}{r1,r2,r6}{el,}_defconfig <BOARDS="list of boards"> Where BOARDS is some subset of the following: boston ni169445 ranchu sead-3 xilfpga Specifically the following generic default configurations are supported: 32r1_defconfig - Build generic kernel for MIPS32 r1 32r1el_defconfig - Build generic kernel for MIPS32 r1 little endian 32r2_defconfig - Build generic kernel for MIPS32 r2 32r2el_defconfig - Build generic kernel for MIPS32 r2 little endian 32r6_defconfig - Build generic kernel for MIPS32 r6 32r6el_defconfig - Build generic kernel for MIPS32 r6 little endian 64r1_defconfig - Build generic kernel for MIPS64 r1 64r1el_defconfig - Build generic kernel for MIPS64 r1 little endian 64r2_defconfig - Build generic kernel for MIPS64 r2 64r2el_defconfig - Build generic kernel for MIPS64 r2 little endian 64r6_defconfig - Build generic kernel for MIPS64 r6 64r6el_defconfig - Build generic kernel for MIPS64 r6 little endian micro32r2_defconfig - Build generic kernel for microMIPS32 r2 micro32r2el_defconfig - Build generic kernel for microMIPS32 r2 little endian The following legacy default configurations have been converted to generic and can still be used: sead3_defconfig - Build 32r2el_defconfig BOARDS=sead-3 sead3micro_defconfig - Build micro32r2el_defconfig BOARDS=sead-3 xilfpga_defconfig - Build 32r2el_defconfig BOARDS=xilfpga ...
