I wrote it before ARM started down the DT direction and all these
formalities were developed.

We continue to use it here, there is just no way to autodetect flash
partition layouts. I'm not fussed about having to change to something
else in future.

The reason the original patch exposed the cmdline parser is because
that is how the internal mechanisms work - but realistically, the
cmdline parser is a hack to get around the lack of DT partition
description. If the DT can describe the partitions it should supersede
and obsolete the old command line hack. IMHO

That is why it is prefixed with linux, the review of the part parser name is
the responsibility of the MTD crew, not the DT folks.

bcm47xxpart seems like a terrible name for a partition scheme. Really,
almost any scheme can be used on any SOC, naming a partition parser
after a SOC family makes very little sense to me..
