If a board is booting from NAND, then it is required that the boot jumpers are correctly set to specify NAND boot mode and the NAND type (8-bit versus 16-bit width, for example). I revisited all the i.mx boards that use MXC_NAND driver and could not see anyone using 16-bit NAND (ie, no 16-bit NAND IOMUX setting), so it is safe to assume that all the current boards are using 8-bit width NAND. If a board has 16-bit width NAND, then the boot jumpers need to reflect that and CONFIG_SYS_NAND_BUSWIDTH_16BIT must be specified in the config file. So I don't envision any breakage here.
