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 = "/[EMAIL PROTECTED]/[EMAIL PROTECTED]";
ethernet1 = "/[EMAIL PROTECTED]/[EMAIL PROTECTED]";
serial0 = "/[EMAIL PROTECTED]/[EMAIL PROTECTED]";
serial1 = "/[EMAIL PROTECTED]/[EMAIL PROTECTED]";
pci0 = "/[EMAIL PROTECTED]";
};
=> fdt print ethernet0
[EMAIL PROTECTED] {
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>;
};

I thought it would be useful to add this hint to the "help fdt" printout.
I replace the "quoting special characters" note since it is only slightly
useful - hopefully quoting special characters is second nature to our
target audience.
If nobody has any objections to this and the previously posted libfdt
update changesets, I plan to issue a u-boot-fdt pull request by Monday.
Best regards,
