[U-Boot-Users] Scripting in ppcboot 1.1.5

[Chris Elston]

As I have been finding out, the hush shell in PPCBoot is severely limited.
It doesn't have support for shell variables (and many other things too, much
of hush.c is #ifdef'd out).  You could try using "setenv" to set a PPCBoot
environment variable, but I think you'll have more luck writing a c program
(see examples/hello_world.c for an example of a c program that uses PPCBoot
monitor functions for I/O)

Hope this helps,

Chris.
