Seems that I screwed up something with mpfs_ethernet, while merging accross branches. I'll check that again |
This adds initialization of the ksz9477 switch when used instead of a PHY, directly connected to SGMII Signed-off-by: Jukka Laitinen <jukkax@ssrc.tii.ae>

Summary
This adds an initial management driver for ksz9477 ethernet switch, and takes it into use in mpfs platform.
Implemented so far:
Impact
This allows using ksz9477 switch to be used instead of an ethernet phy, allowing to make a network device with multiple ports
Testing
Tested on a custom HW design where Microchip PolarFire SOC is connected via SGMII and I2C to the switch ASIC.
