Moving to the driver model requires CONFIG_DM to be enabled. Currently several boards like kmeter1_defconfig produce a build error when CONFIG_DM is enabled:

In file included from include/common.h:35, from ./arch/powerpc/include/asm/fsl_lbc.h:10, from include/mpc83xx.h:10, from ./arch/powerpc/include/asm/ppc.h:27, from ./arch/powerpc/include/asm/u-boot.h:18, from include/dm/of.h:10, from include/dm/ofnode.h:12, from include/dm/device.h:13, from include/linux/mtd/mtd.h:26, from drivers/mtd/mtdconcat.c:25: include/image.h: In function ‘image_check_target_arch’: include/image.h:846:3: error: #error "please define IH_ARCH_DEFAULT in your arch asm/u-boot.h" # error "please define IH_ARCH_DEFAULT in your arch asm/u-boot.h" ^~~~~ include/image.h:848:31: error: ‘IH_ARCH_DEFAULT’ undeclared (first use in this function); did you mean ‘IH_ARCH_COUNT’? return image_check_arch(hdr, IH_ARCH_DEFAULT);

The error can be avoided by moving the definition of IH_ARCH_DEFAULT before

#include <asm/ppc.h>
