| 13 | Marvell Aquantia Ethernet PHY require a firmware to be loaded to actually |
| 14 | work. |
| 15 | |
| 16 | This can be done and is implemented by OEM in 3 different way: |
| 17 | - Attached SPI flash directly to the PHY with the firmware. The PHY |
| 18 | will self load the firmware in the presence of this configuration. |
| 19 | - Read from a dedicated partition on system NAND declared in an |
| 20 | NVMEM cell, and loaded to the PHY using its mailbox interface. |
| 21 | - Manually provided firmware loaded from a file in the filesystem. |
