Hello All,



I am working on an AST2600 based OpenBMC project where we are
using Ethernet Switch KSZ9893R.



Microchip KSZ9893R is a 3-Port Gigabit Ethernet Switches with
RGMII/MII/RMII Interface.



I investigated OpenBMC/Uboot for KSZ9893R support but could not find it GitHub
- openbmc/u-boot: OpenBMC "Das U-Boot" Source Tree
<https://github.com/openbmc/u-boot>.



After further investigation, I found this driver is already upstream at
mainline Uboot :
https://github.com/u-boot/u-boot/blob/master/drivers/net/ksz9477.c



Can anyone please take a look and get this driver in the OpenBMC tree?



Thank you in advance for your help.



Regards,

Sushil Dubey
