You can try fixing the IP and MAC address for the board in u-boot itself and not keep them volatile to be picked up from your DHCP host. You can even specify the file to be picked up from which server (IP), then you can get the OS image
But I am not getting why you want to pull the file over DHCP. If you are working on umon, you can very well pull the file to TFS via TFTP. It can load the uClinux.elf and a BIN file as well. That itself serves the purpose. You need not have u-boot itself. You can set the flag to boot uClinux from TFS.
Else you can try integrating TFS with u-boot. I know it's a big job, but....it will be great. u-boot will take another big leap.
Thanks and Regards

I am running uboot 1.1.5 and I have uClinux image that include kernel and romfs. I download to my board (M5272C3 based) using tftpboot. Everything looks fine but, dhcpcd failed to get ip address and Ethernet packet transmit kept timeout. Buffer descriptor got dumped eveny few seconds. The same image (elf file instead of bin file) download under umon that works fine on that part. Anyone has idea? Oh, I have set my Ethernet address, but it did not help.
Thanks!
