+Subject: [PATCH] nvmem: u-boot-env: post-process "ethaddr" env variable
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+U-Boot environment variables are stored in ASCII format so "ethaddr"
+requires parsing into binary to make it work with Ethernet interfaces.
+
+This includes support for indexes to support #nvmem-cell-cells = <1>.
