This patchset fixes exactly that issue! No need to fix it twice :-)

I just tested it again, and actually realized that I made an error in
the third patch which does not allow to select SPL_DFU_SUPPORT. 

Adding this:
 config SPL_DFU_SUPPORT
        bool "Support DFU (Device Firmware Upgarde)"
-       depends on SPL_GADGET_SUPPORT
+       depends on SPL_USB_GADGET_SUPPORT
        select SPL_HASH_SUPPORT
        help
          This feature enables the DFU (Device Firmware Upgarde) in SPL
with


Allows to select SPL / TPL  ---> Suppport USB Gadget drivers, and
Support DFU (Device Firmware Upgarde). This compiles fine now.

Will send a v3 which integrates that fix.
