Does your script also cater for .dts files not matching any pattern,
but including a .dtsi file that does match a pattern?

I assume I built everything after moving, but maybe not...

That's all just "details". First, we need agreement on a) moving
things to subdirs and b) doing it 1-by-1 or all at once. So far we've
been stuck on a) for being 'too much churn'.

Sorry for missing most of the discussion last week. The script sounds
fine to me, the only reason I didn't want to do this in the past is that
we had the plan to move platforms out of the kernel tree to an external
repository and I wanted to do this platform at a time and also only move
each one once. I don't think that is going to happen anytime soon now,
so let's just do your script.

Can you send me the script and/or a pull request of the resulting
tree based on my soc/dt branch? Everything is merged upstream,
and I think git-merge would handle the remaining merges with any
other changes in mainline.

I've dusted off my script and made a branch[1] with the result.
There's just a couple of fixes needed after the script is run (see the
top commit). The cross arch includes are all fixed up by the script.
dtbs_install maintains a flat install. I compared the number of .dtbs
before and after to check the script.

I think the only issue remaining is finalizing the mapping of
platforms to subdirs. What I have currently is a mixture of SoC
families and vendors. The most notable are all the Freescale/NXP
platforms, pxa, socfpga, and stm32. It's not consistent with arm64
either. Once that's finalized, I still need to go update MAINTAINERS.

Here's the current mapping:

Ack we're trying to get rid of meson, so it would be time.
