[bug report] sunxi: H6: no ethernet on Orange Pi One Plus

[Anne Macedo]

Hey!

I'm trying to bake Linux images for the Orange Pi One Plus using Yocto.
Everything works fine, except for Ethernet.

On the u-boot prompt:

=> dhcp
No ethernet found.

After adding:

CONFIG_SPL_SPI_SUNXI=y
CONFIG_SUN8I_EMAC=y

to configs/orangepi_one_plus_defconfig, I started seeing this error:

=> dhcp
sun8i_emac_eth_start: Timeout

I saw this other bug report but I couldn't really understand what has
been made to fix this issue [1].

More context here [2].
