Hello,
I've set up a computer with Asus KGPE-D16 recently. I use an Winbond W25Q64.V 8M flash chip and tested with this config with only ROM size changed:
https://review.coreboot.org/gitweb/cgit/board-status.git/tree/asus/kgpe-d16/...
And it can boot to my OS on disk. However, after I enabled the serial console, I can only see: "FCH SPI: Too much to write. Does your SPI chip driver use spi_crop_chunk()?"
Do you see any other messages at all from a cold start (i.e. AC power removed from the system, then reapplied after 15 seconds while the serial console is being logged)?
I have not personally tested the 8M chips; it could be that there is an issue with coreboot's generic driver for those devices. I know it's not a general issue with large Flash chips since the 16M chips work fine.
Thanks!

I have other console logs, but not about this SPI issue, I came into other problems when I try other configurations.
I don't know if it's related to serial console. The config on board status and the ROMs from libreboot all boots, but they all have no serial console output.

Thanks for the info.

It seems that as long as I enable serial console output, system cannot boot. Besides the SPI thing, I can also get stuck on some place when booting. Now I post these logs in the attachment. Both logs are logged when I'm using a 2MB flash chip.
