These are the aliases: => fdt p /aliases aliases { ethernet0 = "/qe at e0100000/ucc at 2000"; ethernet1 = "/qe at e0100000/ucc at 3000"; serial0 = "/soc8360 at e0000000/serial at 4500"; serial1 = "/soc8360 at e0000000/serial at 4600"; pci0 = "/pci at e0008500"; }; Dereference an alias by not using the '/' prefix per OF conventions: => fdt print ethernet0 ucc at 2000 { device_type = "network"; compatible = "ucc_geth"; cell-index = <0x1>; reg = <0x2000 0x200>; interrupts = <0x20>; interrupt-parent = <0x2>; local-mac-address = [00 00 00 00 00 00]; rx-clock-name = "none"; tx-clock-name = "clk9"; phy-handle = <0x3>; phy-connection-type = "rgmii-id"; pio-handle = <0x4>; }; Whooo-heeee! Dereference the ethernet0 alias and print a property: => fdt print ethernet0/phy-connection-type libfdt fdt_path_offset() returned FDT_ERR_NOTFOUND Doh doh doh! :-) Pretty close, though. I'll have to dig into this a bit more to see why the alias expansion doesn't seem to work with properties, check how it behaves with nested nodes (maybe). I've rebased u-boot-fdt against u-boot and pushed David's (and other's) libfdt improvements to u-boot-fdt. This is *NOT* ready to be merged into the mainline, but I've made it available in case others want to play with it. Warning: I will be rebasing u-boot-fdt as Wolfgang merges more changes into the mainline. I have not seen problems with rebasing, but YMMV. Best regards, gvb
