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