[U-Boot-Users] Adding stuff and make it compiled

Hi, I've written some new commands for the serial shell using the recommendations enclosed in /docs. I've put all my stuff inside /common because the changes are not board specific. Even though I've changed /common/Makefile adding the new .o files that I want to have built, the compilation process still ignores my modifications, not compiling my new stuff. For the moment, I haven't put conditional statement for preprocessing. I'm wondering whether I've miss some steps.

Thanx
