I think it's very convenient especially if you just want to boot the kernel off
TFTP like with most reference designs. I compile a U-Boot with a command
string like so as default:
set serverip ; set ipaddr ; tftpboot
0x80000000 Image ; tftpboot 0x83000000 juno.dtb ; booti 0x80000000 -

Then I can just compile a kernel I want to test and reboot and it
will download and boot whatever I just compiled quick and nice
with no keyboard interaction.
