Re: [Buildroot] PYNQ Z2: new board support contribution question

[Rutherther via buildroot]

Hello,

I have made support for Pynq Z2 board locally (though most of it is off
of work of others that submitted patch to u-boot), and wanted to
contribute it.

The thing is, this board is not supported in u-boot / linux, at least
not yet. This means that the device tree and ps7 init have to be added
to buildroot in order to support it, so I wanted to ask:

1. Is it fine to put those files to buildroot, or does the support first
   have to come in u-boot/linux in order for buildroot to support it as well?
2. If so, what way is preferred:
  a. Patches for u-boot and linux
  b. Set custom path to ps7 init and device tree

  Currently I have it implemented as a. It will probably be a bit harder
  to do with u-boot with b as I am not sure how to pass the device tree
  file from buildroot to u-boot, with linux it's clear.

Thanks,
Rutherther
