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 bootargs = "console=ttyS0,115200 earlyprintk"; 71 stdout-path = &uart0; 72 }; 73 74 memory { 75 device_type = "memory"; 76 reg = <0 0x00000000 0 0x40000000>; /* 1GB */ 77 }; 78 79 soc { 80 ranges = <MBUS_ID(0xf0, 0x01) 0 0 0xf1000000 0x100000 81 MBUS_ID(0x01, 0x1d) 0 0 0xfff00000 0x100000>; 82 83 pcie-controller { 84 status = "okay"; 85 86 /* 87 * Connected to Marvell 88SX7042 SATA-II controller 88 * handling the four disks. 89 */ 90 pcie@1,0 { 91 /* Port 0, Lane 0 */ 92 status = "okay"; 93 }; 94 95 /* 96 * Connected to EtronTech EJ168A XHCI controller 97 * providing the two rear USB 3.0 ports. 98 */ 99 pcie@5,0 { 100 /* Port 1, Lane 0 */ 101 status = "okay"; 102 }; 103 }; 104 105 internal-regs { 106 107 /* RTC is provided by Seiko S-35390A below */ 108 rtc@10300 { 109 status = "disabled"; 110 }; 111 112 spi0: spi@10600 { 113 status = "okay"; 114 115 spi-flash@0 { 116 #address-cells = <1>; 117 #size-cells = <1>; 118 compatible = "micron,n25q064"; 119 reg = <0>; /* Chip select 0 */ 120 spi-max-frequency = <20000000>; 121 122 /* 123 * Warning! 124 * 125 * Synology u-boot uses its compiled-in environment 126 * and it seems Synology did not care to change u-boot 127 * default configuration in order to allow saving a 128 * modified environment at a sensible location.
