Arria 10 : Kernel Configuration Setting for customised board

Hello ,

I am designing linux OS for our custom board which took reference from Arria 10 SoC. While building u-boot , I did changes in qsys for all the hardware modification at HPS side , so that a .sof file is generated which build a uboot_mkpimage.bin .

But I am confused with the kernel configuration , I took reference from
which indicated that a dtb file is generated which is required to boot linux kernel.
This file is generated using sopcinfo and board xml files.
In order to boot the custom board , do we need to make any change in sopcinfo or board xml files , as we did in uboot build ?
If so ,how to modify xml files?

please do reply.
