[U-Boot] Obtaining board specific phy diagnostics

[Matthew Lear]

Hi all,

Is there a common mechanism to hook in board specific ethernet phy
commands? For example, I'd like to hook in the ability to read the TDR
characteristics of the ethernet cable connected to my board. I know the
phy on my board supports this so I was planning on hooking it into the
mii command set somehow.

Currently, the ethernet set up code registers phy read and write
routines, but that is all. Is there a recognised method / approach to
add such board specific commands/features into an existing 'common' command?

Cheers,
--  Matt

A board specific command is fine, so using U_BOOT_CMD.
