If you are in this * situation, you should either update your bootloader (preferred * solution) or the below Device Tree should be adjusted. */ /dts-v1/; #include "armada-xp-98dx3336.dtsi" / { model = "DB-XC3-24G4XG"; compatible = "marvell,db-xc3-24g4xg", "marvell,armadaxp-98dx3336", "marvell,armada-370-xp"; chosen { bootargs = "console=ttyS0,115200 earlyprintk"; }; memory { device_type = "memory"; reg = <0 0x00000000 0 0x40000000>; /* 1 GB */ }; }; &devbus_bootcs { status = "okay"; /* Device Bus parameters are required */ /* Read parameters */ devbus,bus-width = <16>; devbus,turn-off-ps = <60000>; devbus,badr-skew-ps = <0>; devbus,acc-first-ps = <124000>; devbus,acc-next-ps = <248000>; devbus,rd-setup-ps = <0>; devbus,rd-hold-ps = <0>; /* Write parameters */ devbus,sync-enable = <0>; devbus,wr-high-ps = <60000>; devbus,wr-low-ps = <60000>; devbus,ale-wr-ps = <60000>; }; &uart0 { status = "okay"; }; &uart1 { status = "okay"; }; &i2c0 { clock-frequency = <100000>; status = "okay"; }; &nand { status = "okay"; num-cs = <1>; marvell,nand-keep-config; marvell,nand-enable-arbiter; nand-on-flash-bbt; nand-ecc-strength = <4>; nand-ecc-step-size = <512>; }; &spi0 { status = "okay"; spi-flash@0 { #address-cells = <1>; #size-cells = <1>; compatible = "m25p64"; reg = <0>; /* Chip select 0 */ spi-max-frequency = <20000000>; m25p,fast-read; partition@u-boot { reg = <0x00000000 0x00100000>; label = "u-boot"; }; partition@u-boot-env { reg = <0x00100000 0x00040000>; label = "u-boot-env"; }; partition@unused { reg = <0x00140000 0x00ec0000>; label = "unused"; }; }; };
