Arria U-boot 2022.04 device tree for SDMMC build

Hello all, while working on building a custom SDMMC boot image for my custom board i noticed there is a dtsi file named "socfpga_arria10_socdk_sdmmc-u-boot.dtsi ". My question is. Is this parameter being handled by this configuration in defconfig?
will the Makefile in u-boot find the "socfpga_arria10_socdk_sdmmc-u-boot.dtsi " by adding the extra string inside the dts Makefile during build process?

I’ve searched the entire u-boot folder for the commands that handle this particular dtsi but only able to find it inside arch/doc/README.socfpga which is not very helpful, not sure if i missed anything haha.
The reason I am asking this is that I am customizing the “sdmmc-u-boot-dtsi” file therefore I’ll have to rename it.
