Consider separating the USB code and the Flash code to make a generic CDC module

[TomKeddie]

Luke, the bootloader is a fabulous concept but the CDC portion has much wider applicability. It would make a great virtual uart peripheral for an HDL cpu for instance. You've done a great job of modularising the code, perhaps the CDC could be moved to a separate repo and imported into the bootloader as a module. Once separate the API to the CDC block could be clarified with some doco or perhaps wrapped as a wishbone peripheral?
