/*
 * 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
