Thank you Naresh, I added the missing PCH device id following your advise, also enabled DEBUG_BOOT_STATE but I am still not able to get more information via serial debug about the exact location of the problem (but now I am certain is in the coreboot code not in FSP).
I suspect the code involved aound this issue is hardwaremain.c and device.c.... Only the first "boot" just after flash I notice that the ethernet and SATA LEDs blink for a fraction of a second then reboots. After that, the following attempts to boot I don't see LED activity neither reboots, just halted in some kind of loop. According to the serial dump the las printed text is "0x71" but my question is if the serial port gets broken still during "BS_DEV_INIT_CHIPS" or is already doing "BS_DEV_ENUMERATE". As Naresh pointed my PCH H chipset "Kabylake-H HM175" was not added to the list; I added it but may be is needed to do something else to make it work. Or istill is misconfigured (attached my .config file for your review)... I someone has a similar system working and want to share its configuration files to compare them myself I will be grateful.
