[U-Boot-Users] custom loadable command shell

[Andrew Wozniak]

Hi,

I've been contemplating how to develop a U-Boot loadable applet which 
provides a set of custom commands which augment the standard U-Boot 
command set. The general idea is to keep a working version of U-Boot in 
Flash without modifying - and then simply installing the new command 
applet as it changes.

The applet would include a command parser. If none of my custom commands 
are found, a call to the U-Boot parser (via ABI) would be made to handle 
U-Boot commands.

This is just a concept phase and I was hoping to get some opinions on 
the feasibility and obstacle of this approach.

Thanks for all comments. Andy
