14 * NOTE: The original firmware from Samsung can only boot ARM32 kernels.
15 * Unfortunately, the firmware is signed and cannot be replaced easily.
16 * There seems to be no way to boot ARM64 kernels on this device at the moment,
17 * even though the hardware would support it.
18 *
19 * However, it is possible to use this device tree by compiling an ARM32 kernel
20 * instead. For clarity and build testing this device tree is maintained next
21 * to the other MSM8916 device trees. However, it is actually used through
