Maybe add MACH_APF9328=y to mx1_defconfig?

If you use imx_add_platform_device to register the device
apf9328_flash_data and flash_resource can be moved to .init.rodata. For
some extra points introduce imx_add_physmap_flash.

ditto, extra points for imx_add_dm9000

This shouldn't be needed with a modern boot loader.
