Your patch works. Thank you!
This is the first time I post a bug report on a mailing list. I hope I have included the right recipients.
The network adapter of this board is affected by another bug for which I have found a partial solution. I will send a separate message to discuss the issue.

This commit likely prevents the activation of the option CONFIG_RTL8211X_PHY_FORCE_MASTER needed for proper gigabit networking on this device. Since the only modification introduced by this commit was moving Kconfig files, I suspect this change may affect many more devices as well for which proper build options may not be enabled.
