Building for am335x_evm and am335x_evm_usbspl should tell you if it is,
or is not.  Whacking network support into SPL required more than
--gc-sections alone could give us and we needed to drop a few
couldn't-ever-reach calls and functionality out.

Yes, I tried to build for am335x_evm without this ifdef, no problem.
Whether it can be removed?
