* 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
