For the BMC connector patch, you know if there is a register setting I can check to see if a BMC is present or not ?

I think you can use VGA CRD0[7] whose definition is as below:

DRAM Initial Selection (see note 1)
0: VBIOS Initial the DRAM
1: SOC Firmware Initial the DRAM

If CRD0[7] is 1, there is BMC.

Thank you. That seems very helpful.

Thank a lot, I will run some tests, and add this check in my v6.
