+		 * There are 3 types of reserved memory regions here:
+		 * 1. Firmware related regions.
+		 *     This will be described as: reserved-region@address. Current
+		 * reserved-region may have reserved area which was not yet used,
+		 * release note of the firmware can have such kind of information.
+		 * 2. Firmware related which shared with kernel access.
+		 *     Each region will have a specific node with specific label
+		 * name for later phandle reference from other driver dt node. May
+		 * overlapping with above type regions.
+		 * 3. PIL regions.
+		 *     PIL regions are allocated by kernel and assigned to subsystem
+		 * firmware later.
+		 * Here is a map for this platform:
+		 * 0x100000000 +------------------+
+		 *             |                  |
+		 *             | Firmware Related |
+		 *             |                  |
+		 *  0xd8000000 +------------------+
+		 *             |                  |
+		 *             | Kernel Available |
+		 *             |                  |
+		 *  0xA7000000 +------------------+
+		 *             |                  |
+		 *             |    PIL Region    |
+		 *             |                  |
+		 *  0x8BC00000 +------------------+
+		 *             |                  |
+		 *             | Firmware Related |
+		 *             |                  |
+		 *  0x80000000 +------------------+
+		 * Note that:
+		 * 1. 0xA7000000 to 0xA8000000 was used by bootloader as well, not
+		 * suggest for other usage.
+		 * 2. Kernel start address was start at 0xA8000000.
