I noticed you asked for a reference to the original hush code that is the origin for U-Boot's adaptation. I couldn't find a reply to that question. I also haven't been able to find anything with a quick we search. Do you know where it did come from?
I never got a response, but it appears to be busybox...
Oops, sorry. Yes, of course it is busybox.
As far as I can tell, it was added around October 2001 to the PPCBoot project as part of the PPCBoot v1.1.0 release:
* Added "hush" shell (from Busybox) as alternative command line interpreter, thus enabling powerful command line syntax like if...then...else...fi conditionals or `&&' and '||' constructs ("shell scripts").
See the README file for information about implementation and usage.
Best regards,
Wolfgang Denk
