RE: [Ltib] how to build a kernel module using ltib? (docu)

[D'Abbraccio Joe-ljd015]

Note: When you are in the kernel configuration menus, you can type /USB to 
search for USB related config options and how to find them in the menu tree.

For the USB config:

USB_FILE_STORAGE [=n]
Prompt: File-backed Storage Gadget
  Defined at drivers/usb/gadget/Kconfig:371
  Depends on: <choice>
  Location:
    -> Device Drivers
      -> USB support
        -> USB Gadget Support
          -> USB Gadget Drivers (<choice> [=y])

Here is a complete list of USB setting that I have used successfully to do the 
gadget file operation on the MPC8349E-mITX platform (I have omitted many 
options that are not set).
