Oops! I should have shared why the patches are needed.
You're correct.
- My platform has the 88x2110.
- The MACTYPE setting of strap pin on the platform is SXGMII.
- However, we realized that the SoC cannot communicate the PHY with SXGMII
because of mismatching hardware specification.
- We have a lot of boards which mismatch the MACTYPE setting.
So, I would like to change the MACTYPE as SGMII by software for the platform.
Best regards,
Yoshihiro Shimoda
