I’d really like to keep this for all SUN8I_EMAC configurations, as we
need the PHY support to initialise the pad timing parameters from the
DTS. If these are not initialised, then RGMII (i.e. Gigabit) will not work.

As we are moving towards a ‘universal’ U-Boot binary for sun50i and
try to put all board specific info into the DTS, I’d like to keep this in
sunxi-common.h to ensure that nobody rebuild without it and then
has issues on our boards.

Regards,
Philipp.
