		/* These are 3 types of reserved memory regions here:
		 * 1. Firmware related regions which aren't shared with kernel.
		 *     The device tree source in kernel doesn't need to have node to
		 * indicate the firmware related reserved information. Bootloader
		 * conveys the information by updating devicetree at runtime.
		 *     This will be described as: UEFI saves the physical address of
		 * the UEFI System Table to dts file's chosen node. Kernel read this
		 * table and add reserved memory regions to efi config table. Current
		 * reserved memory region may have reserved region which was not yet
		 * used, release note of the firmware have such kind of information.
		 * 2. Firmware related memory regions which are shared with Kernel
		 *     The device tree source in the kernel needs to include nodes
		 * that indicate fimware-related shared information. A label name
		 * is suggested because this type of shared information needs to
		 * be referenced by specific drivers for handling purposes.
		 *     Unlike previous platforms, QCS8550 boots using EFI and describes
		 * most reserved regions in the ESRT memory map. As a result, reserved
		 * memory regions which aren't relevant to the kernel(like the hypervisor
		 ( region) don't need to be described in DT.
		 * 3. Remoteproc regions.
		 *     Remoteproc regions will be reserved and then assigned to
		 * subsystem firmware later.
		 * Here is a reserved memory map for this platform:
		 *  0x80000000 +-------------------+
		 *             |                   |
		 *             | Firmware Related  |
		 *             |                   |
		 *  0x8a800000 +-------------------+
		 *             |                   |
		 *             | Remoteproc Region |
		 *             |                   |
		 *  0xa7000000 +-------------------+
		 *             |                   |
		 *             | Kernel Available  |
		 *             |                   |
		 *  0xd4d00000 +-------------------+
		 *             |                   |
		 *             | Firmware Related  |
		 *             |                   |
		 * 0x100000000 +-------------------+
