From 7e2805c203a6c8dc85c1cfda205161ed39ae82d5 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Tue, 4 Apr 2023 18:21:41 +0100 Subject: [PATCH] dt-bindings: nvmem: u-boot,env: add MAC's #nvmem-cell-cells MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit U-Boot's "ethaddr" environment variable is very often used to store *base* MAC address. It's used as a base for calculating addresses for multiple interfaces. It's done by adding proper values. Actual offsets are picked by manufacturers and vary across devices.
