CME9210: U-Boot with net-console?

Does anybody tried to configure u-boot to use net-console instead of an UART?

I’ve tried to add to build/U-Boot/include/configs/cme9210.h line:

#define CONFIG_NETCONSOLE /* include NetConsole support
*/

Got this:
Description Resource Path Location Type

make: *** [uboot] Error 2 cme9210uboot 0 C/C++

so it does not seem to work
