[U-Boot] auto-update and DHCP

[Beaman, Thomas]

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
