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:
