This looks like board setup behaviour.  Shouldn't setting this up be

done directly by the platform setup function (in other=20

Besides, you want

Upon further review of all this I don't think this belongs in the =20
kernel at all.  This is one time setup and should be done in firmware.

The latest u-boot supports the serdes initialization for 837x.
So, it can be dropped from kernel for now.
