/*
* 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
* arch/arm/boot/dts/qcom-msm8916-samsung-grandmax.dts
