From ba4e95c9f0e18ddeff55ef1b94be650d7b653d3f Mon Sep 17 00:00:00 2001 From: Lukasz Majewski Date: Tue, 17 Sep 2013 15:58:21 +0200 Subject: usb:g_dnl:ums: Conditional compilation for mass storage function (f_mass_storage) 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.
