There are currently 3 in-flight series that adds glues to DW XPCS and stmmac:

This one,
The Rockchip one from Coia [1]
The S32 one from Jan [2]

MAINTAINERS entry for XPCS says :

It would nice if some of you could help maintain the core XPCS driver, and make sure
these series aren't stepping on one another :( I personnaly don't have any XPCS HW
for tests.

You don't have to do it alone, multiple people can co-maintain that :) Maybe
Synopsys folks can also chime in ?
