Subject: [PATCH v2 18/20] arm64: dts: ls1028a: sl28: get MAC addresses from VPD
Date: Fri, 2 Sep 2022 00:18:55 +0200 [thread overview]
Message-ID: <20220901221857.2600340-19-michael@walle.cc> (raw)
In-Reply-To: <20220901221857.2600340-1-michael@walle.cc>
Now that it is finally possible to get the MAC addresses from the OTP
memory, use it to set the addresses of the network devices.
There are 8 reserved MAC addresses in total per board. Distribute them
as follows:
+----------+------+------+------+------+------+
| | var1 | var2 | var3 | var4 | kbox |
+----------+------+------+------+------+------+
| enetc #0 | +0 | | | +0 | +0 |
| enetc #1 | | | +0 | +1 | +1 |
| enetc #2 | rand | rand | rand | rand | rand |
| enetc #3 | | | | | |
| felix p0 | | +0 | | | +4 |
| felix p1 | | +1 | | | +5 |
| felix p2 | | | | | +6 |
| felix p3 | | | | | +7 |
| felix p4 | | | | | |
| felix p5 | | | | | |
+----------+------+------+------+------+------+
An empty cell means, the port is not available and thus doesn't need an
ethernet address.
