17		/* These are 3 types of reserved memory regions here:
18		 * 1. Firmware related regions which aren't shared with kernel.
19		 *     The device tree source in kernel doesn't need to have node to
20		 * indicate the firmware related reserved information. Bootloader
21		 * conveys the information by updating devicetree at runtime.
22		 *     This will be described as: UEFI saves the physical address of
23		 * the UEFI System Table to dts file's chosen node. Kernel read this
24		 * table and add reserved memory regions to efi config table. Current
25		 * reserved memory region may have reserved region which was not yet
26		 * used, release note of the firmware have such kind of information.
27		 * 2. Firmware related memory regions which are shared with Kernel
28		 *     The device tree source in the kernel needs to include nodes
29		 * that indicate fimware-related shared information. A label name
30		 * is suggested because this type of shared information needs to
31		 * be referenced by specific drivers for handling purposes.
32		 *     Unlike previous platforms, QCS8550 boots using EFI and describes
33		 * most reserved regions in the ESRT memory map. As a result, reserved
34		 * memory regions which aren't relevant to the kernel(like the hypervisor
35		 ( region) don't need to be described in DT.
36		 * 3. Remoteproc regions.
37		 *     Remoteproc regions will be reserved and then assigned to
38		 * subsystem firmware later.
39		 * Here is a reserved memory map for this platform:
40		 *  0x80000000 +-------------------+
