[OpenWrt-Devel] When to use Target Profile or Subtarget

I'm adapting the "Freescale MPC83xx" platform, so that multiple devices
can be selected.
Actually the following boards are in use, but hard-coded over files or
file-patches and not selectable be "menuconfig"
- RouterBOARD 333
- RouterBOARD 600
This makes it unnecessary difficult to add new devices.

I've "scanned" on other platforms to see how this is generally done.
There seems to be three "mainstreams":
"Target Profile" to select the Board implementation (like
"Subtarget" to select the Board implementation (like
"A1x/XBurst/AU1x00/RT288x"), or
a mix of both.

Is there a "official definition" when to use what?
The difference is not obvious to me.

Mit freundlichen Grüßen / Best regards
