The problem is that commit fe9ca3d3287185 ("hush: fix some quoted
variable expansion issues") in U-Boot breaks this command in boot.scr.

 setenv catcat setenv catout\;'setenv catX "setenv catout '\\\\\\\''\$\$catin'\\\\\\\''"' \; run catX

Reverting that commit from U-Boot fixes the script problem, then you'll
need to set a few more variables to get the full boot working:
