[U-Boot] how to use a function provided by u-boot in linux driver

Hi All, I would like to use miiphy_read and miiphy_write functions provided by u-boot in the linux kernel driver. This is required for reading the link status of each of the phys associated with a switch.

I added miiphy_read and miiphy_write to the exports.h and tried to use it in the kernel. But we get lots of multiple reference errors as some libraries will be there both in u-boot and linux kernel.

Could I do something like a dll or lib for these functions and use them in the linux kernel driver ? Please guide me on this.

Thanks, Kartheek N S
