Subject: [Buildroot] [PATCH 1/1] package/rpi-firmware: add overlays/README
Date: Mon, 31 Oct 2022 11:46:43 +0000 [thread overview]
Message-ID: <20221031114643.6648-1-tim.gover@raspberrypi.com> (raw)
If a custom os_prefix directory is specified then the Raspberry Pi
firmware probes for the README file in overlays directory.
Since the README file is small let's include it, otherwise,
the firmware won't recognize the overlays directory if the user
later moves it to an os_prefix specific sub-directory.
From
https://www.raspberrypi.com/documentation/computers/config_txt.html#overlay_prefix
Unless ${os_prefix}${overlay_prefix}README exists, overlays are shared
with the main OS (i.e. os_prefix is ignored).
