 * NOTE: The original firmware from Samsung can only boot ARM32 kernels.

 * There seems to be no way to boot ARM64 kernels on this device at the moment,

 *
 * However, it is possible to use this device tree by compiling an ARM32 kernel
 * instead. For clarity and build testing this device tree is maintained next
