[U-Boot] Problem with mounting a jffs2 partition on flash.

Hi Marek,

We received information from Altera that we should stick to this previous version of SPL. 
Even if we decide to upgrade U-Boot itself.
I don't know why. They just wrote it. 
Although I will try both variants.

Sorry for confusing you. We tried both variants.
With old version I had problems with creating jffs2/ubifs upon a partition that contains Linux kernel.

My colleague tried to build U-Boot 2016.01. But he failed with hanging U-Boot as a result.
I will try to do it once again and let you know about the results.

I will try to do.

Thanks for that hint.

Yes, exactly. But we have separated SPL and U-Boot images and put them separately (with two commands).

This is the old version (2013).

This is good question on which I'm not ready to answer yet.
I understand that the newer the better, but this is still not an easy decision.
Anyway I will think about that after I will solve my issue with U-Boot .
