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