Subject: [PATCH 2/2] arm64: dts: add NAND board files for Stratix10 and Agilex

From: Dinh Nguyen <[email-masked]>
Date: Fri, 8 Nov 2019 10:33:27 -0600

From: Dinh Nguyen <[email-masked]>

The Stratix10 and Agilex devkits support 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 socfpga_agilex_socdk_nand.dts
