add a widget area to storefront

I need the exact code to place a full width widget area above the standard footer widgets in the woo commerce storefront theme. Please only bid if you are a woo commerce expert who can follow the same format of code that the storefront theme has already. I would like you to provide me with the function to add to functions php and the code to add to footer php. Basically so i am clear it needs to do exactly what the storefront-footer-bar plugin does, but i want it hard coded not as a plugin.
