Add note on dereferencing /aliases pointers
Replace the "must quote special characters" note with a hint on
how to dereference /aliases pointers by omitting the leading "/".
This feature was introduced by Kumar Gala as a libfdt enhancement
in commit ed035708235332c3c117ee3bb1a426063f03cfcb.
Example:
=> fdt print /aliases
aliases {
ethernet0 = "/qe@e0100000/ucc@2000";
ethernet1 = "/qe@e0100000/ucc@3000";
serial0 = "/soc8360@e0000000/serial@4500";
serial1 = "/soc8360@e0000000/serial@4600";
pci0 = "/pci@e0008500";
};
=> fdt print ethernet0
ucc@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>;
};
