TGPIO enabled in Radxa X4 AMI BIOS

#1

I have been talking to Ahmad Byagowi from Meta, he helms the OCP-TAP project which has done a lot of great work getting various small computers working with PTP time sync.

The i226-V NIC on the X4 can support PTP hardware timestamps if, I believe, TGPIO support is enabled in the AMI BIOS, and Ahmad also worked with the LattePanda team to get it enabled on the Mu: https://github.com/LattePandaTeam/LattePanda-Mu/issues/4

If enabled, and T_Sync 0 and T_Sync 1 are exposed somewhere on the board, this could be used for cheap but highly accurate time services.

@ryann, please let me know if you need any help from AMI on the BIOS changes necessary to enable TGPIO.
Also, would you please look into your schematic to see if T_Sync 0 and T_Sync 1 are somehow accessible, at least brought out from under your chipset.
Looking forward to your response.
