It's not. No interface/device found on OS level, neighter during Coreboot init. But the device tree has been modified according to the factory bios.
Line 88: This is probably because the xHCI blob is loaded by the vendor BIOS onto the controllers, >which coreboot should do. Does booting the vendor BIOS, flashing coreboot internally, >powering off the board completely and then booting coreboot result in usable xHCI ports?
Belive me, I tried literally everything. Somehow I managed it to work once on F2A85-M, but never again.
src/mainboard/asus/a88xm-e/Kconfig: Line 29: This works with the ITE IT8603?
Yes, it is. Probably really same chip, just different package pin count. https://lm-sensors.lm-sensors.narkive.com/VnxI9zvt/it8620e-it8623e-vs-it8603...
