No problem, I would submit 2 patches in v2
1 for network driver support and other for board specific changes

OK. I would use allocate memory dynamically for patch version 2

This is a standard global u-boot function which should be defined if
CONFIG_RESET_PHY_R is #defined

Another way is to provide compile time switches.
I wanted to keep this changeable on the board. So that the code does not
need a recompile to change this behavior
I would provide compile switches which can be defined along with board
configuration
