[U-Boot] U-Boot DHCP/BOOTP for ServerIP env

Hi,

Trying to implement a device that boot's from TFTP/NFS using U-boot bootloader. The device can boot from TFTP/NFS fine if we update the "serverip" enviroment variable manualy over console. Is there a way to set this enviroment variable ("serverip") via DHCP? We have configured all other options via DHCP/TFTP. Only this one variable is required to setup manualy. Please help with advice.
