With a multiplatform kernel, once built we always have warp_setup_nand_flash()
called
and NDFC probed, no matter what machine we actually run on. This potentially
can cause
problems (such as kernel crash), since NDFC is probed at a warp-predefined
address.
Using machine_device_initcall() NAND devices are registered if we run on a warp
only.
