(They must be always selected in correct combination.) This is already discussed when I posted the RFC version of the Kconfig series. We can easily do [1] Choose boards by arch Just grep CONFIG_ARM=y, CONFIG_MIPS=y, CONFIG_SANDBOX=y in defconfigs [2] Choose boards by board name It is the file name of defconfigs My question is, do we really need to choose by CPU, Vendor, SoC ? I know they are useful. For ex. nvidia developers probably want to build only Tegra boards. One possible idea I come up with is to have 'board group' in .buildman file so people can build only boards they are interested in. Something like this: ---------->8--------------- [board-alisa] tegra20: harmony seaboard ventana tegra30: beaver tegra114: dalmore tegra124: venice2 tegra: tegra20 tegra30 tegra114 tegra124 -----------8<--------------- With the settings above, "tools/buildman/buildman tegra20" is the same as "tools/buildman/buildman harmony seaboard ventana" "tools/buildman/buildman tegra" is the same as "tools/buildman/buildman tegra20 tegra30 tegra114 tegra124" and also the same as "tools/buildman/buildman harmony seaboard ventana beaver dalmore venice2" We have to setup ~/.buildman at the first run. (and modify it when adding new boards) Better to provide a tool to auto-generate .buildman file?
