On the LS1046A RDB board, to change the ethernet chip from RTL8211FS chip to AR8031 chip, what parts of u-boot and kernel should be modified?

There is no AR8031 PHY on the NXP original LS1046A-RDB, thus no ready recommendations
are available. If you are working with a custom board modeled after
LS1046A-RDB but with a different PHY, the course of actions is as
follows:


1. Identify and compile the kernel driver for your PHY. Consult at the
   PHY manufacturer for driver availability.


2. Edit your Device Tree to reflect your PHY model and connection.
   Details can be found here:
 

   https://source.codeaurora.org/external/qoriq/qoriq-components/linux/tree/Documentation/devicetree/bi...
   
   Contact your PHY driver vendor/maintainer for additional node
   properties required/recognized by the PHY.
   
3. For u-Boot, similar to the above, make sure the driver is enabled
   at build time and look at the board specific code under
   /board/freescale/ls1046ardb/ to see what PHY-related initializations
   are done.


Have a great day,
