From b203e6f1e8336659878b6b604abd2a5fda0d8767 Mon Sep 17 00:00:00 2001 From: Michael Walle Date: Thu, 5 Jan 2023 16:22:30 +0100 Subject: [PATCH] arm64: dts: ls1028a: sl28: get MAC addresses from VPD 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 | | +2 | | | +2 | | enetc #3 | | +3 | | | +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.
