From: Ley Foon Tan <[email protected]> Copied from Linux commit ID 3c0f3b8545e7 ("arm64: dts: add NAND board files for Stratix10 and Agilex")
The Stratix10 devkit supports a separate NAND daughter card. The NAND daughter card replaces the SDMMC slot that is on the default daughter card thus requires a separate board dts file. Add flash0 label to QSPI node to reference it in other dts file later.
