*** 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.
|
||||
|
||||
/ {
|
||||
#address-cells = <1>;
|
