I’ve been searching, googling, etc. If I’ve found the answer I’m not sure, because I’ve not been using yocto/bitbake for very long.

I have a recipe for building u-boot for an embedded Linux system. The u-boot is from a github I am sourcing with custom files added to it. However, what I would prefer to do is pull u-boot from the official source and then copy my files (stored in the recipe) to the source directory before it’s compiled.

I am not sure which method to use to accomplish this.
do_install() seems to be for copying to the rootfs, not the working directory.
