Hi Marek, > The mass storage composite function is now compiled in only when > CONFIG_USB_GADGET_MASS_STORAGE is defined. > Such change provides binary size reduction for boards which use USB > download gadget (like am335x_evm) with DFU, but don't use UMS. > > For example at am335x_evm board reduction is more than 2KiB for > text and around 120B for data. >
