Subject: [PATCH 3/4] dt-bindings: nvmem: u-boot,env: add MAC's #nvmem-cell-cells
Date: Wed, 22 Feb 2023 18:22:44 +0100 [thread overview]
Message-ID: <20230222172245.6313-4-zajec5@gmail.com> (raw)

From: Rafał Miłecki <rafal@milecki.pl>
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.
