I don´t understand the script enough to comment.

We must elaborate a way to document a how-to for mfgtools. Maybe, we
should only add a comment on commit log (for example, for kernel
recipe and u-boot recipe) showing where the deliverable from this
recipe is placed, and what should I copy to mfg-tools dir tree in
order to get it working.

Not a mfg-tools related how-to, only a guide for the generated files.

Please, let me know what you think,


Daiane
