-*** Memory binding ***
-
-The /memory node provides basic information about the address and size
-of the physical memory. This node is usually filled or updated by the
-bootloader, depending on the actual memory configuration of the given
-hardware.
-
-The memory layout is described by the following node:
-
-/ {
-	#address-cells = <(n)>;
-	#size-cells = <(m)>;
-	memory {
-		device_type = "memory";
-		reg =  <(baseaddr1) (size1)
-			(baseaddr2) (size2)
-			...
-			(baseaddrN) (sizeN)>;
-	};
-	...
-};
-
-A memory node follows the typical device tree rules for "reg" property:
-n:		number of cells used to store base address value
-m:		number of cells used to store size value
-baseaddrX:	defines a base address of the defined memory bank
-sizeX:		the size of the defined memory bank
-
-
-More than one memory bank can be defined.
-
-
-*** Reserved memory regions ***
-
-In /memory/reserved-memory node one can create child nodes describing
-particular reserved (excluded from normal use) memory regions. Such
-memory regions are usually designed for the special usage by various
-device drivers. A good example are contiguous memory allocations or
-memory sharing with other operating system on the same hardware board.
-Those special memory regions might depend on the board configuration and
-devices used on the target system.
-
-Parameters for each memory region can be encoded into the device tree
-with the following convention:
-
-[(label):] (name) {
-	compatible = "linux,contiguous-memory-region", "reserved-memory-region";
-	reg = <(address) (size)>;
-	(linux,default-contiguous-region);
-};
-
-compatible:	one or more of:
-	- "linux,contiguous-memory-region" - enables binding of this
-	  region to Contiguous Memory Allocator (special region for
-	  contiguous memory allocations, shared with movable system
-	  memory, Linux kernel-specific).
-	- "reserved-memory-region" - compatibility is defined, given
-	  region is assigned for exclusive usage for by the respective
-	  devices.
-
-reg:	standard property defining the base address and size of
-	the memory region
-
-linux,default-contiguous-region: property indicating that the region
-	is the default region for all contiguous memory
-	allocations, Linux specific (optional)
-
-It is optional to specify the base address, so if one wants to use
-autoconfiguration of the base address, '0' can be specified as a base
-address in the 'reg' property.
-
-The /memory/reserved-memory node must contain the same #address-cells
-and #size-cells value as the root node.
-
-
-*** Device node's properties ***
-
-Once regions in the /memory/reserved-memory node have been defined, they
-may be referenced by other device nodes. Bindings that wish to reference
-memory regions should explicitly document their use of the following
-property:
-
-memory-region = <&phandle_to_defined_region>;
-
-This property indicates that the device driver should use the memory
-region pointed by the given phandle.
-
-
-*** Example ***
-
-This example defines a memory consisting of 4 memory banks. 3 contiguous
-regions are defined for Linux kernel, one default of all device drivers
-(named contig_mem, placed at 0x72000000, 64MiB), one dedicated to the
-framebuffer device (labelled display_mem, placed at 0x78000000, 8MiB)
-and one for multimedia processing (labelled multimedia_mem, placed at
-0x77000000, 64MiB). 'display_mem' region is then assigned to fb@12300000
-device for DMA memory allocations (Linux kernel drivers will use CMA is
-available or dma-exclusive usage otherwise). 'multimedia_mem' is
-assigned to scaler@12500000 and codec@12600000 devices for contiguous
-memory allocations when CMA driver is enabled.
-
-The reason for creating a separate region for framebuffer device is to
-match the framebuffer base address to the one configured by bootloader,
-so once Linux kernel drivers starts no glitches on the displayed boot
-logo appears. Scaller and codec drivers should share the memory
-allocations.
