Our motivation is to boot the OS over the network using FTP ( because it is going to be more secure with login/passwd credentials, before file-transfer), instead of TFTP. Hence we are exploring the option of FTP client in U-Boot.. If not, we are looking for any "Authenticated" file transfer over network in existing U_boot.
