This is just an example. What if I chose "-a arm" and "-v freescale". ARM has
300+ targets, but only 20+ are for Freescale. I could save time by building a
lot less platforms.

The point here is the "OR" logic.

Yes. MAKEALL also generates the boards.cfg.

Again it is our internal tools of choice. We use Gerrit and Jenkins. Each commit
triggers a build on Jenkins. Right now I use MAKEALL to build the concerned
targets. Before each build, the working directory is checkout out to that
particular commit and cleaned. So if each build needs to generate the
boards.cfg, a lot of time will be consumed if I have many commits in the queue.

But generating boards.cfg is not caused by your patch. I just point out what I saw.
