* plat_get_fdt() - Return a pointer to the platform's device tree blob
*
* This function provides a platform independent API to get a pointer to the
* flattened device tree blob. The interface between bootloader and kernel
* is not consistent across platforms so it is necessary to provide this
* API such that common startup code can locate the FDT.
*
* This is used by the KASLR code to get command line arguments and random
* seed from the device tree. Any platform wishing to use KASLR should
* provide this API and select SYS_SUPPORTS_RELOCATABLE.
*
* Return: Pointer to the flattened device tree blob.
