One is used for regular booting, the other is treated as 12 fallback. 13 14 This binding allows defining all fixed partitions and marking those containing 15 firmware. System can use that information e.g. for booting or flashing 16 purposes. 17 18maintainers: 19 - Rafał Miłecki <rafal@milecki.pl> 20 21properties: 22 compatible: 23 const: linksys,ns-partitions 24 25 "#address-cells": 26 enum: [ 1, 2 ] 27 28 "#size-cells": 29 enum: [ 1, 2 ] 30 31patternProperties: 32 "^partition@[0-9a-f]+$": 33 $ref: "partition.yaml#" 34 properties: 35 compatible: 36 items: 37 - const: linksys,ns-firmware 38 - const: brcm,trx 39 unevaluatedProperties: false 40 41required: 42 - "#address-cells" 43 - "#size-cells" 44 45additionalProperties: false 46 47examples: 48 - | 49 partitions { 50 compatible = "linksys,ns-partitions"; 51 #address-cells = <1>; 52 #size-cells = <1>; 53 54 partition@0 { 55 label = "boot"; 56 reg = <0x0 0x100000>; 57 read-only; 58 }; 59 60 partition@100000 { 61 label = "nvram"; 62 reg = <0x100000 0x100000>; 63 }; 64 65 partition@200000 { 66 compatible = "linksys,ns-firmware", "brcm,trx"; 67 reg = <0x200000 0xf00000>; 68 }; 69 70 partition@1100000 { 71 compatible = "linksys,ns-firmware", "brcm,trx"; 72 reg = <0x1100000 0xf00000>; 73 }; 74 };
