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

Dear Kartheek N S,

In message 23610373.post@talk.nabble.com you wrote:

 I would like to use miiphy_read and miiphy_write functions provided by

u-boot in the linux kernel driver.

This is not possible, and the request makes no sense.

When Linux boots, all the memory used by U-Boot is freed; no trace of U-Boot is left behind in memory. You cannot call any U-Boot functions from Linux, as U-Boot does not exist any more in RAM.

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

associated with a switch.

Linux has it's own interface and drivers to talk to PHYs and the like.

Best regards,

Wolfgang Denk
