+ * NOTE: The original firmware from Samsung can only boot ARM32 kernels on some
+ * variants.
+ * Unfortunately, the firmware is signed and cannot be replaced easily.
+ * There seems to be no way to boot ARM64 kernels on 32-bit devices at the
+ * moment, even though the hardware would support it.
+ *
+ * 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
+ * to the other MSM8916 device trees. However, it is actually used through
