This patch introduces some cleanups to ums code. Changes: ums common: - introduce UMS_START_SECTOR and UMS_NUM_SECTORS as defined in usb_mass_storage.h both default values as 0 if board config doesn't define them common cleanup changes: - change name of struct "ums_board_info" to "ums" - "ums_device" fields are moved to struct ums and "dev_num" is removed - change function name: board_ums_init to ums_init - remove "extern" prefixes from usb_mass_storage.h cmd_usb_mass_storage: - change error() to printf() if need to print info message - change return values to command_ret_t type at ums command code - add command usage string Changes v2: ums common: - always returns number of read/write sectors - coding style clean-up ums gadget: - calculate amount of read/write from device returned value.
