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-370.dtsi" 63 64/ { 65 model = "Synology DS213j"; 66 compatible = "synology,ds213j", "marvell,armada370", 67 "marvell,armada-370-xp"; 68 69 chosen { 70 stdout-path = "serial0:115200n8"; 71 }; 72 73 memory { 74 device_type = "memory"; 75 reg = <0x00000000 0x20000000>; /* 512 MB */ 76 }; 77 78 soc { 79 ranges = <MBUS_ID(0xf0, 0x01) 0 0xf1000000 0x100000 80 MBUS_ID(0x01, 0xe0) 0 0xfff00000 0x100000>; 81 82 internal-regs { 83 84 /* RTC provided by Seiko S-35390A I2C RTC chip below */ 85 rtc@10300 { 86 status = "disabled"; 87 }; 88 89 spi0: spi@10600 { 90 status = "okay"; 91 92 spi-flash@0 { 93 #address-cells = <1>; 94 #size-cells = <1>; 95 compatible = "micron,n25q064"; 96 reg = <0>; /* Chip select 0 */ 97 spi-max-frequency = <20000000>; 98 99 /* 100 * Warning! 101 * 102 * Synology u-boot uses its compiled-in environment 103 * and it seems Synology did not care to change u-boot 104 * default configuration in order to allow saving a 105 * modified environment at a sensible location.
