ARM: Terasic DE0-Nano-SoC/Atlas-SoC: Use upstream compatible string
The upstream (Linux) 'compatible' string for the Terasic DE0-Nano-SoC/Atlas-SoC board in "dts/src/arm/socfpga_cyclone5_de0_nano_soc.dts" differs from the barebox 'compatible' string for the same board in "arch/arm/dts/socfpga_cyclone5_de0_nano_soc.dts": Linux: "terasic,de0-atlas" barebox: "terasic,de0-nano-soc" That results in an incompatibility when trying to boot a bootloader spec entry with a 'devicetree' key that refers to the DTB file built from the Linux sources. The barebox bootloader spec loader will ignore the entry because the 'compatible' string in the root node of the DTB does not match what barebox expects. Remove the 'compatible' string list from "arch/arm/dts/socfpga_cyclone5_de0_nano_soc.dts" so that barebox uses the upstream compatible string list. Also remove the 'model' string ("Terasic DE0-Nano-SoC/Atlas-SoC Kit") so that barebox uses the upstream (and shorter!) model name ("Terasic DE-0(Atlas)"). Finally, update the `of_machine_is_compatible("terasic,de0-nano-soc")` function call in `socfpga_init()` to use the "terasic,de0-atlas" string.
