Everything needed to boot goes into the initrd now days so you don't
even need the SD card.
Check the URL above. The setup described there uses a sdcard with a
u-boot script, which kicks off the tftp boot.
I don't see the point in using tftp, you can place kernel+initrd
directly at the sdcard if you have one anyway.
Another possible way would be to boot directly from iscsi like you can
do on x86 with an sanboot-enabled iPXE rom. I have no idea whenever
u-boot can handle that though.
