In some cases, it doesn't make sense to do so. Because:
a) These firmwares are just raw binary files, they don't need any build or
   process. They are only useful when we try to create a bootable image.
b) There firmwares may be licensed under a proprietary license. We may not
   integrate them to a fully open source build system. But we do want to provide
   an easy way for the customer to build a bootable image.

Thanks,
Kevin
