For example: "make xxx_defcofnig yyy_defconfig" After doing this operation, .config file will be created according to these two defconfig xxx_defcofnig and yyy_defconfig.

Do you want to build xxx_defconfig and yyy_defconfig as two separate configurations and two separate builds ? Or do you want to combine them together because each describes only one part of the overall system ?

Then: $ ./support/kconfig/merge_config.sh fragment1 fragment2 see also https://bootlin.com/doc/training/buildroot/buildroot-slides.pdf slides 43 and 44. However, I would recommend to *not* store fragments under configs/ with a _defconfig suffix, as this is normally used for complete defconfigs, not fragments.

Are there guidelines for where defconfig fragments _can_ be stored, how they should be structured, named, what they can contain? All the files that I see in the configs/ folder are simple defconfigs.

All the > files that I see in the configs/ folder are simple defconfigs. They can be stored wherever you want, and there are no particular guidelines on how they should be structured. Each project will have its own constraints. What matters is that Buildroot takes as input a single .config file: how this .config file is produced is not relevant to Buildroot.
