Subject: Re: [PATCH] build: put DT "compatible" value as "board_name" in
profiles.json
I think the question is therefore more on how to deal with devices that do
not use DT? If we use a per device rootfs a line could be added to /etc/os-
release containing something like OPENWRT_PROFILE="SpEcIaL-CaSEv100",
which is then shown via `ubus call system borad`.
Well, one could just use something like this, which we had before the
compatible was used:
https://github.com/openwrt/openwrt/blob/openwrt-19.07/target/linux/ramips/base-files/lib/ramips.sh
That's exactly what I was thinking about. That file does:
echo "$name" > /tmp/sysinfo/board_name
which means device-specific identifier will appear as $(board_name)
There, one could just use the "profile names" instead, with "_" replaced by ","
for the few non-DT targets.
However, this assumes a 1-to-1 relation between boards and profiles, and I'm
not sure whether that always exists.
And somebody would have to create that by hand.
Right. That list should be easy to verify by looking at Makefile and
platform.sh / ramips.sh.
But I somehow lost track what's the ultimate goal of the proposed changes here,
so maybe I'm not going into the right direction with this.
I described it shortly in commit message as:

More details: we are working on firmware updating apps that find device
appropriate firmware automatically. See luci-app-attendedsysupgrade for
example.
We need a way for such apps to:
1. Get device identifier (like $(board_name))
2. Easily find matching firmware in profiles.json using above identifier
