Hi Kartheek,

 I would like to use miiphy_read and miiphy_write functions provided by

u-boot in the linux kernel driver.

Why would you want to do such a weird thing?

By the time Linux boots, U-Boot will be completely overwritten in memory. After all, Linux is perfectly able to care for itself ;)

 This is required for reading the link status of each of the phys

associated with a switch.

So implement similar code in the Linux driver.

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.

We do not do such a form of sharing. Actually we copy much code from Linux to U-Boot - the other way is rather seldom - and then we try to keep the code exatly the same as in Linux to allow for easy updates in the future.

Cheers Detlev
