+Subject: [04/13] arm64: dts: rockchip: Add NOR flash to ODROID-M1
+Origin: https://git.kernel.org/linus/9f96204b7dcf94d03cad41194447c665d10675b7
+
+Enable the Rockchip Serial Flash Controller for the ODROID-M1 and add
+the corresponding SPI NOR flash entry. The SFC is used in dual I/O mode
+and not quad I/O mode, as the FSPI_D2 pin is shared with the EMMC_RSTn
+pin.
+
+The partitions addresses and sizes are taken from the ODROID-M1
+Partition Table page on the ODROID wiki.
