[Buildroot] Include binary firmware blob in image

[Patrick Doyle]

Short version:
What is the best way to include a binary firmware blob fetched from
GitHub in a buildroot image?

Long version:
I am using the wilc1003_firmware.bin file available in the
https://github.com/linux4sc/wireless-firmware GitHub repository.  It
needs to be installed in /lib/firmware/atmel on my rootfs.

I could certainly write a post_build.sh script to clone the repo and
copy the file to the rootfs, but this doesn't feel like the most
buildroot-esque way to do this.  I feel like I should create a package
(where should I put it in the menu hierarchy?) and use that.

Is there an existing example I could follow for this sort of package?

Can folks recommend any tips or tricks for writing this package from scratch?

Take a look at package/zd1211-firmware, or package/ux500-firmware.
Or if it's lots of firmware options/choices, then package/linux-firmware.
