Actually u-boot commandline support some simple scripts.
I mean something like that:

U-Boot 2015.04-imx_v2015.04_4.1.15_1.0.0_ga+g0fa2a52 (Apr 30 2016 - 00:27:47)
...
Hit any key to stop autoboot: 0
=>
=> echo 1 ; sleep 5 ; echo 2
1
2
=>

So you can make a script that performs your fuse programming commands one by one.

Have a great day,
Victor
