When the arbitration between NOR and NAND flash is enabled the <FORCE_CSX> field bit[21] in the Data Flash Control Register needs to be set to 1 according to guidleine GL-5830741.
This patch introduces a new compatible string "marvell,nand-force-csx" which is activated through device tree to implement the guideline GL-5830741.
