8 * NOTE: The original firmware from Samsung can only boot ARM32 kernels on some
9 * variants.
10 * Unfortunately, the firmware is signed and cannot be replaced easily.
11 * There seems to be no way to boot ARM64 kernels on 32-bit devices at the
12 * moment, even though the hardware would support it.
13 *
14 * However, it is possible to use this device tree by compiling an ARM32 kernel
15 * instead. For clarity and build testing this device tree is maintained next
16 * to the other MSM8916 device trees. However, it is actually used through
17 * arch/arm/boot/dts/qcom-msm8916-samsung-e5.dts
