[U-Boot] uboot for ARRIA10 SoC

Hi,

I am using Intel/Altera REF board: Arria 10 SoC development kit part number DK-SOC-10AS066S-A. I am using Altera/Intel tools to generate an uboot image which include the devictree.dts and it is build with mkpimage. Has anybody ported the Altera/Intel Arria 10Soc to the open source uboot and able to build an uboot image using open source uboot and open source toolchain? Thanks Claudio
