It is used in recent versions of 48 * DSM software provided by Synology. Nonetheless, some earlier boards 49 * were delivered with an older version of u-boot that left internal 50 * registers mapped at 0xd0000000. If you have such a device you will 51 * not be able to directly boot a kernel based on this Device Tree. In 52 * that case, the preferred solution is to update your bootloader (e.g. 53 * by upgrading to latest version of DSM, or building a new one and 54 * installing it from u-boot prompt) or adjust the Devive Tree 55 * (s/0xf1000000/0xd0000000/ in 'ranges' below). 56 */ 57 58/dts-v1/; 59 60#include <dt-bindings/input/input.h> 61#include <dt-bindings/gpio/gpio.h> 62#include "armada-xp-mv78230.dtsi" 63 64/ { 65 model = "Synology DS414"; 66 compatible = "synology,ds414", "marvell,armadaxp-mv78230", 67 "marvell,armadaxp", "marvell,armada-370-xp"; 68 69 chosen { 70 stdout-path = "serial0:115200n8"; 71 }; 72 73 memory { 74 device_type = "memory"; 75 reg = <0 0x00000000 0 0x40000000>; /* 1GB */ 76 }; 77 78 soc { 79 ranges = <MBUS_ID(0xf0, 0x01) 0 0 0xf1000000 0x100000 80 MBUS_ID(0x01, 0x1d) 0 0 0xfff00000 0x100000>; 81 82 pcie-controller { 83 status = "okay"; 84 85 /* 86 * Connected to Marvell 88SX7042 SATA-II controller 87 * handling the four disks. 88 */ 89 pcie@1,0 { 90 /* Port 0, Lane 0 */ 91 status = "okay"; 92 }; 93 94 /* 95 * Connected to EtronTech EJ168A XHCI controller 96 * providing the two rear USB 3.0 ports. 97 */ 98 pcie@5,0 { 99 /* Port 1, Lane 0 */ 100 status = "okay"; 101 }; 102 }; 103 104 internal-regs { 105 106 /* RTC is provided by Seiko S-35390A below */ 107 rtc@10300 { 108 status = "disabled"; 109 }; 110 111 spi0: spi@10600 { 112 status = "okay"; 113 114 spi-flash@0 { 115 #address-cells = <1>; 116 #size-cells = <1>; 117 compatible = "micron,n25q064"; 118 reg = <0>; /* Chip select 0 */ 119 spi-max-frequency = <20000000>; 120 121 /* 122 * Warning! 123 * 124 * Synology u-boot uses its compiled-in environment 125 * and it seems Synology did not care to change u-boot 126 * default configuration in order to allow saving a 127 * modified environment at a sensible location.
