I don't think it has been discussed much on the mailing list or IRC.
The early platform devices have not been used much outside of arch/sh
and arch/arm/mach-shmobile, and those only use it for clocksource and
serial.
Now we have a new method for both of these, at least with DT, so
my impression is that we won't need the early_platform support in
the future. One of the problems with the current interface is that
it requires statically declaring platform_device structures, which is
something that has been on Greg's list of device model antipatterns
for a long time.

Ok, good.
