I tried testing this series on SEI510, but I must still be missing some
defconfig options, as the default defconfig doesn't lead to a working
interface.

I tried adding this kconfig fragment[1], and the dwmac probes/inits but
I must still be missing something, as the dwmac is still failing to find
a PHY.  Boot log: https://termbin.com/ivf3

I have the same result testing on the u200.
