Hi!

We already do this kind of a programming in board/altera/socfpga/socfpga.c
in board_phy_config(), don't we ?

Also, see [1], once I apply this, the DT support (not DM) for SoCFPGA will
become mandatory. Won't it make more sense to pull these values from the
DT instead of poluting the board environment with those please ?

Thanks!
