[ptxdist] [PATCH 0/2] Add support for device tree overlays

[Michael Riesch <michael.riesch@wolfvision.net>]

Hi all,

This series introduces support for device tree overlays in ptxdist.
The first patch makes the dtb compilation routine more general and
adds suitable helpers for the overlay generation, which can be used
by any package.
The second patch activates the support for overlays for the kernel
package.

This series was inspired by Christian Melki's RFC in June 2021 [0]
but implements a slightly more general approach as *every* package
can generate device tree overlays here. This is envisaged to come in
handy for e.g., firmware or FPGA bitstream packages that alter the
hardware description. I had some discussions with Michael Tretter
about this flexible approach that I gratefully acknowledge at this
point.

Looking forward to your comments!

Best regards,
Michael
