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 MBUS_ID(0x09, 0x09) 0 0 0xf1100000 0x10000 80 MBUS_ID(0x09, 0x05) 0 0 0xf1110000 0x10000>; 81 82 devbus-bootcs { 83 status = "okay"; 84 85 /* Device Bus parameters are required */ 86 87 /* Read parameters */ 88 devbus,bus-width = <16>; 89 devbus,turn-off-ps = <60000>; 90 devbus,badr-skew-ps = <0>; 91 devbus,acc-first-ps = <124000>; 92 devbus,acc-next-ps = <248000>; 93 devbus,rd-setup-ps = <0>; 94 devbus,rd-hold-ps = <0>; 95 96 /* Write parameters */ 97 devbus,sync-enable = <0>; 98 devbus,wr-high-ps = <60000>; 99 devbus,wr-low-ps = <60000>; 100 devbus,ale-wr-ps = <60000>; 101 102 /* NOR 16 MiB */ 103 nor@0 { 104 compatible = "cfi-flash"; 105 reg = <0 0x1000000>; 106 bank-width = <2>; 107 }; 108 }; 109 110 pcie-controller { 111 status = "okay"; 112 113 /* 114 * All 6 slots are physically present as 115 * standard PCIe slots on the board. 116 */ 117 pcie@1,0 { 118 /* Port 0, Lane 0 */ 119 status = "okay"; 120 }; 121 pcie@2,0 { 122 /* Port 0, Lane 1 */ 123 status = "okay"; 124 }; 125 pcie@3,0 { 126 /* Port 0, Lane 2 */ 127 status = "okay"; 128 }; 129 pcie@4,0 { 130 /* Port 0, Lane 3 */ 131 status = "okay"; 132 }; 133 pcie@9,0 { 134 /* Port 2, Lane 0 */ 135 status = "okay"; 136 }; 137 pcie@10,0 { 138 /* Port 3, Lane 0 */ 139 status = "okay"; 140 }; 141 }; 142 143 internal-regs { 144 serial@12000 { 145 status = "okay"; 146 }; 147 serial@12100 { 148 status = "okay"; 149 }; 150 serial@12200 { 151 status = "okay"; 152 }; 153 serial@12300 { 154 status = "okay"; 155 }; 156 157 sata@a0000 { 158 nr-ports = <2>; 159 status = "okay"; 160 }; 161 162 mdio { 163 phy0: ethernet-phy@0 { 164 reg = <0>; 165 }; 166 167 phy1: ethernet-phy@1 { 168 reg = <1>; 169 }; 170 171 phy2: ethernet-phy@2 { 172 reg = <25>; 173 }; 174 175 phy3: ethernet-phy@3 { 176 reg = <27>; 177 }; 178 }; 179 180 ethernet@70000 { 181 status = "okay"; 182 phy = <&phy0>; 183 phy-mode = "rgmii-id"; 184 }; 185 ethernet@74000 { 186 status = "okay"; 187 phy = <&phy1>; 188 phy-mode = "rgmii-id"; 189 }; 190 ethernet@30000 { 191 status = "okay"; 192 phy = <&phy2>; 193 phy-mode = "sgmii"; 194 }; 195 ethernet@34000 { 196 status = "okay"; 197 phy = <&phy3>; 198 phy-mode = "sgmii"; 199 }; 200 201 mvsdio@d4000 { 202 pinctrl-0 = <&sdio_pins>; 203 pinctrl-names = "default"; 204 status = "okay"; 205 /* No CD or WP GPIOs */ 206 broken-cd; 207 }; 208 209 usb@50000 { 210 status = "okay"; 211 }; 212 213 usb@51000 { 214 status = "okay"; 215 }; 216 217 usb@52000 { 218 status = "okay"; 219 }; 220 221 spi0: spi@10600 { 222 status = "okay"; 223 224 spi-flash@0 { 225 #address-cells = <1>; 226 #size-cells = <1>; 227 compatible = "m25p64", "jedec,spi-nor"; 228 reg = <0>; /* Chip select 0 */ 229 spi-max-frequency = <20000000>; 230 }; 231 }; 232 }; 233 }; 234}; 235
