I'm afraid it's not so clear cut.
True, you can use dtc on the host to dump a blob to DTS in a similar
manner to fdtdump (with the prettified output is much better with this
patch).
Although the size of the dtc compiler package is larger than fdtdump by
about 5 times (this is not that important nowdays), the biggest use is
for restricted environment where the full dtc compiler just can't work.
A bootloader or something small can easily incorporate fdtdump for
dumping out blobs, while including dtc is not even be possible.
Anyway, the purpose of this patch is to make an already existing tool
better. If you feel that strongly about it duplicating functionality you
should just remove it and leave it at that.
