I suppose your kernel doesn't include these definitions.

The Linux kernel has a commproc.h file very similar to the one in u-boot. You will have to add the definitions you find for your board in the u-boot file, into the linux version of the same file.

When I see the comproc.h file, these Macros arn't defined for FADS Board.. Any clues ?

Note: The Ethernet hardware work very fine with u-boot, using which I do my tftpboot .

Seems your Linux kernel configuration is broken, and/or your Linux kernel source does not really support your hardware configuration.

In any case, such a question is off topic on u-boot-users
