The 0xf1000000 is the default used by the recent, 52 * DT-capable, U-Boot bootloaders provided by Marvell. Some earlier 53 * boards were delivered with an older version of the bootloader that 54 * left internal registers mapped at 0xd0000000. If you are in this 55 * situation, you should either update your bootloader (preferred 56 * solution) or the below Device Tree should be adjusted. 57 */ 58 59/dts-v1/; 60#include "armada-xp-mv78460.dtsi" 61 62/ { 63 model = "Marvell Armada XP Evaluation Board"; 64 compatible = "marvell,axp-db", "marvell,armadaxp-mv78460", "marvell,armadaxp", "marvell,armada-370-xp"; 65 66 chosen { 67 stdout-path = "serial0:115200n8"; 68 }; 69 70 memory { 71 device_type = "memory"; 72 reg = <0 0x00000000 0 0x80000000>; /* 2 GB */ 73 }; 74 75 soc { 76 ranges = <MBUS_ID(0xf0, 0x01) 0 0 0xf1000000 0x100000 77 MBUS_ID(0x01, 0x1d) 0 0 0xfff00000 0x100000 78 MBUS_ID(0x01, 0x2f) 0 0 0xf0000000 0x1000000>; 79 80 devbus-bootcs { 81 status = "okay"; 82 83 /* Device Bus parameters are required */ 84 85 /* Read parameters */ 86 devbus,bus-width = <16>; 87 devbus,turn-off-ps = <60000>; 88 devbus,badr-skew-ps = <0>; 89 devbus,acc-first-ps = <124000>; 90 devbus,acc-next-ps = <248000>; 91 devbus,rd-setup-ps = <0>; 92 devbus,rd-hold-ps = <0>; 93 94 /* Write parameters */ 95 devbus,sync-enable = <0>; 96 devbus,wr-high-ps = <60000>; 97 devbus,wr-low-ps = <60000>; 98 devbus,ale-wr-ps = <60000>; 99 100 /* NOR 16 MiB */ 101 nor@0 { 102 compatible = "cfi-flash"; 103 reg = <0 0x1000000>; 104 bank-width = <2>; 105 }; 106 }; 107 108 pcie-controller { 109 status = "okay"; 110 111 /* 112 * All 6 slots are physically present as 113 * standard PCIe slots on the board. 114 */ 115 pcie@1,0 { 116 /* Port 0, Lane 0 */ 117 status = "okay"; 118 }; 119 pcie@2,0 { 120 /* Port 0, Lane 1 */ 121 status = "okay"; 122 }; 123 pcie@3,0 { 124 /* Port 0, Lane 2 */ 125 status = "okay"; 126 }; 127 pcie@4,0 { 128 /* Port 0, Lane 3 */ 129 status = "okay"; 130 }; 131 pcie@9,0 { 132 /* Port 2, Lane 0 */ 133 status = "okay"; 134 }; 135 pcie@10,0 { 136 /* Port 3, Lane 0 */ 137 status = "okay"; 138 }; 139 }; 140 141 internal-regs { 142 serial@12000 { 143 status = "okay"; 144 }; 145 serial@12100 { 146 status = "okay"; 147 }; 148 serial@12200 { 149 status = "okay"; 150 }; 151 serial@12300 { 152 status = "okay"; 153 }; 154 155 sata@a0000 { 156 nr-ports = <2>; 157 status = "okay"; 158 }; 159 160 mdio { 161 phy0: ethernet-phy@0 { 162 reg = <0>; 163 }; 164 165 phy1: ethernet-phy@1 { 166 reg = <1>; 167 }; 168 169 phy2: ethernet-phy@2 { 170 reg = <25>; 171 }; 172 173 phy3: ethernet-phy@3 { 174 reg = <27>; 175 }; 176 }; 177 178 ethernet@70000 { 179 status = "okay"; 180 phy = <&phy0>; 181 phy-mode = "rgmii-id"; 182 }; 183 ethernet@74000 { 184 status = "okay"; 185 phy = <&phy1>; 186 phy-mode = "rgmii-id"; 187 }; 188 ethernet@30000 { 189 status = "okay"; 190 phy = <&phy2>; 191 phy-mode = "sgmii"; 192 }; 193 ethernet@34000 { 194 status = "okay"; 195 phy = <&phy3>; 196 phy-mode = "sgmii"; 197 }; 198 199 mvsdio@d4000 { 200 pinctrl-0 = <&sdio_pins>; 201 pinctrl-names = "default"; 202 status = "okay"; 203 /* No CD or WP GPIOs */ 204 broken-cd; 205 }; 206 207 usb@50000 { 208 status = "okay"; 209 }; 210 211 usb@51000 { 212 status = "okay"; 213 }; 214 215 usb@52000 { 216 status = "okay"; 217 }; 218 219 spi0: spi@10600 { 220 status = "okay"; 221 222 spi-flash@0 { 223 #address-cells = <1>; 224 #size-cells = <1>; 225 compatible = "m25p64"; 226 reg = <0>; /* Chip select 0 */ 227 spi-max-frequency = <20000000>; 228 }; 229 }; 230 }; 231 }; 232}; 233
