0012 * NOTE: The original firmware from Samsung can only boot ARM32 kernels.

0014 * There seems to be no way to boot ARM64 kernels on this device at the moment,
0015 * even though the hardware would support it.
0016 *
0017 * However, it is possible to use this device tree by compiling an ARM32 kernel
0018 * instead. For clarity and build testing this device tree is maintained next
0019 * to the other MSM8916 device trees. However, it is actually used through
