He is asking the following:
I am using the BPI-R1 board. When I connect to a specific switch hub 100M Full duplex is not supported. Looking for a solution to resolve this issue
Does your link partner specific switch hub support AN?
If it's not, you have to configure your 53125 port at 100Mbps force mode via gphy MII Control Register Reg(0x10-0x14: 0x00) and disable the 1000Mbps capability via 1000BASE-T Control Register(0x10-0x14: 0x12).
