[U-Boot] imx6, spl and falcon boot

[Chaves, Kevin]

Ok is there documentation anywhere that can show the requirements for supporting SPL if I'd like to be able to implement it, same with falcon mode? I've already got support for nitrogen6x through another vendor but they won't support the spl.

I'm taking a look at board/woodburn/woodburn.c to see what was done for another board that supports SPL. It just looks like void board_init_f(ulong dummy) needs to be implemented for the SPL. 

Someone recommend I look at another set of patch notes that have better docs, but I see it mostly has the falcon mode in it. http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/146987/focus=147040

We've recently switched to uboot/linux from wince and I'm trying to understand how configuring uboot works. I'm also trying to find out how to use the SPL framework and possibly falcon mode with a i.mx6 nitrogen6x board. I'd be delighted if any one could help!

I haven't used spl and falcon mode, so I can't help with these.

Regarding the general support for the i.mx6 nitrogen6x this isn't in U-Boot mainline, yet.

Try to git pull the most recent U-Boot mainline from git://git.denx.de/u-boot.git [1] and apply the patch

http://patchwork.ozlabs.org/patch/216991/

You should then be able to build one of the supported boards

nitrogen6q
nitrogen6dl
nitrogen6s
nitrogen6q2g
nitrogen6dl2g
nitrogen6s1g

by

make nitrogen6xxx_config
make

(replace the 'xxx' with the ending matching your board, e.g. 'q' if you have a Quad board).

Best regards
