 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:
