+		 * 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. OS bootloader
+		 * conveys the information by update device tree in 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.
+		 *     Each region has a specific node with specific label name for
+		 * later phandle reference from other driver dt node.
+		 * 3. PIL regions.
+		 *     PIL regions will be reserved and then assigned to subsystem
+		 * firmware later.
+		 * Here is a reserved memory map for this platform:
+		 * 0x100000000 +------------------+
+		 *             |                  |
+		 *             | Firmware Related |
+		 *             |                  |
+		 *  0xd4d00000 +------------------+
+		 *             |                  |
+		 *             | Kernel Available |
+		 *             |                  |
+		 *  0xa7000000 +------------------+
+		 *             |                  |
+		 *             |    PIL Region    |
+		 *             |                  |
+		 *  0x8a800000 +------------------+
+		 *             |                  |
+		 *             | Firmware Related |
+		 *             |                  |
+		 *  0x80000000 +------------------+
+		 * Note that:
+		 * 0xa7000000..0xA8000000 is used by bootloader, when kernel boot up,
+		 * it is available for kernel usage. This region is not suggested to
+		 * be used by kernel features like ramoops, suspend resume etc.
