I have a Tower evaluation board, and I would like to program the QSPI flash over USB. I have downloaded the MFG Tool for Vybrid, which comes packaged with u-boot. I want to re-compile u-boot after I make some modifications to the source. I am using a virtual machine with Ubuntu 16.10 to execute the build.

I know that u-boot can be configured using the 'make menuconfig' command. I would like to know what Symbols must be set in order to enable the USB Download gadget, to allow me to program the QSPI flash using the MFG Tool.
