1Generic on-chip SRAM
2
3Simple IO memory regions to be managed by the genalloc API.
4
5Required properties:
6
7- compatible : mmio-sram
8
9- reg : SRAM iomem address range
10
11Reserving sram areas:
12---------------------
13
14Each child of the sram node specifies a region of reserved memory. Each
15child node should use a 'reg' property to specify a specific range of
16reserved memory.
17
18Following the generic-names recommended practice, node names should
19reflect the purpose of the node. Unit address (@<address>) should be
20appended to the name.
21
22Required properties in the sram node:
23
24- #address-cells, #size-cells : should use the same values as the root node
25- ranges : standard definition, should translate from local addresses
26           within the sram to bus addresses
27
28Required properties in the area nodes:
29
30- reg : iomem address range, relative to the SRAM range
31
32Optional properties in the area nodes:
33
34- compatible : standard definition, should contain a vendor specific string
35               in the form <vendor>,[<device>-]<usage>
36
37Example:
38
39sram: sram@5c000000 {
40	compatible = "mmio-sram";
41	reg = <0x5c000000 0x40000>; /* 256 KiB SRAM at address 0x5c000000 */
42
43	#adress-cells = <1>;
44	#size-cells = <1>;
45	ranges = <0 0x5c000000 0x40000>;
46
47	smp-sram@100 {
48		compatible = "socvendor,smp-sram";
49		reg = <0x100 0x50>;
50	};
51};
