[U-Boot] auto-update and DHCP

Hi,

I would like to use the auto-update feature that is enabled with CONFIG_UPDATE_TFTP, which requires that the env variable serverip be set for the tftp access. Our system uses DHCP to get the serverip env variable, but this happens after the auto-update attempt has run. I have not been able to find any documentation on using CONFIG_UPDATE_TFTP with DHCP, any ideas on how to setup this configuration.

Thanks, Tom
