There's long running debate on where some symbols should be for a better overall experience of enabling features. > However, looking at the meaning of that symbol, it seems it governs > something else -- USB ethernet device(s) (like the USB-ethernet adapter > which you plug into USB host port).

Does it make more sense to really add one (not misnamed one) or not > ? We should re-work things as needed so that we have more Kconfig symbols, as needed. There's some overlap / overloading of things today as platforms have been able to (and I think am335x_evm is still one that builds for) supporting making a USB RNDIS gadget device happen in SPL, so that we can then be fed the next stage of U-Boot. -- Tom
