Do we have the firmware for the dedicated KBC for this board? I'm looking for a dump of the W25Q16JVZPIQ at U7602 which is used by the IT8258E-248A at U7601.

I think you need check AMD chipset

The laptop boots and works fine aside from the keyboard, which is not detected. I dumped the firmware for the aforementioned keyboard controller, which, mind you, is separate from the EC on this model, and it's blank. 0xFF for the whole file.
