Dear Remy,
In message 3efb10970812270130n429d5853l930a69d784e7855d@mail.gmail.com you wrote:
This is different per architecture, and not properly explained in the readme and the faq.
Please feel free to contribute and improve the documentation...
Is the memory there really always free?
On PowerPC: yes.
But, why is this information on the FAQ still not in the README? This is what most people tend to read first...
Well, IMO the user ("user" in the sense of one who uses an already running U-Boot) is supposed to read the manual first, while the README (and even more the project pages in the wiki) are important for a developer (one who configures, builds and runs U-Boot). As such, command usage (as for the "go" command) is expected to be found in the manual. Implementation and porting details can be found in the doc/README.standalone file, which is IMO ok, too. I think it makes no sense to litter the README with all information about everything. YMMV, of course.
Best regards,
Wolfgang Denk
