| 4 | Subject: [PATCH] arm64: dts: broadcom: bcm4908: add Ethernet MAC addr |
| 5 | MIME-Version: 1.0 |
| 6 | Content-Type: text/plain; charset=UTF-8 |
| 7 | Content-Transfer-Encoding: 8bit |
| 8 | |
| 9 | On most BCM4908 devices MAC address can be read from the bootloader |
| 10 | binary section containing device settings. Use NVMEM to describe that. |
