Thanks for taking the time Arnd and Viresh

The spear1380 is not supported in mainline but it's quite similar to 1310 and 1340.
The spear13xx comes in a few flavors. 1310 and 1340 are the standard ones sold by ST and the 1380 are the customized version for Schneider Electric needs. One part of the chip is customizable but the base is the same in all 13xx. So a few IP blocks differ between the flavors. I can try to send you the 1380 stuff as well.
 
There is currently no external source tree for our kernel easy available.

If the AUXDATA on 3xx is a problem I can try to start focus on sending for patches in that area. We have patches that move some more parts over to devicetree (compared to mainline) but we haven't converted all. I will investigate if we have something that helps in that area.

Thanks,
Mattias Wallin
