Just create your Buildroot configuration, and then run:
make savedefconfig
It will create a file named 'defconfig', which you can simply move to
configs/<foo>_defconfig.
You can also do it in one step like this:
make BR2_DEFCONFIG=configs/<foo>_defconfig savedefconfig
Note that for the board defconfig, we have a few rules in Buildroot:
* The version of the kernel headers and kernel must be fixed (you
should not use the "latest version" option)
* The configuration should be minimal, i.e nothing but the default
userspace package (just Busybox).
Best regards,
Thomas
