[U-Boot] Documentation about Falcon Mode

[Otavio Salvador]

Hello,

During the last U-Boot meeting they "Falcon Mode" has been showed and I'd
like to have more details about it. Where I can find the documentation,
example code and slides?

Regards,

Some documentation is in README (SPL framework) and doc/README.SPL, example
code is in mainline (see i.e. twister board). For slides see [1]. Links to
the videos mentioned in the slides can be found here [2].

Thanks,
Anatolij

I suspect we might need to make this mode more visible, propagate it more. And 
also make the documentation more accessible, that's actually what the people at 
ELCE were complaining about.

You can find the slides of the presentation at the last RMLL in Geneva here:

http://schedule2012.rmll.info/IMG/pdf/LSM2012_UbootFalconMode_Babic.pdf

As example code, you can look at the twister board in mainline. I see
that also the devkit8000 support it.

Guys ... this is not _the_ _problem_ ... :-C

The people at ELCE were really excited by this Falcon mode, it's really the next 
big thing in U-Boot.

But the people were severely disappointed that there is no concise documentation 
for it. So I'm asking you guys who do understand it, can you put together some 
good howto so we can properly advertise this feature? Please!

Best regards,
Marek Vasut

The piece I am missing is how to use u-boot to prepare the saved boot
information used when loading the kernel directly from SPL.

How to make the SPL framework load a kernel image is quite obvious. But
not how to have the right parameters sent to the kernel.

This is right, documentation is missing. I will write down some doc and
post it soon...
