"FCH SPI: Too much to write" on KGPE-D16

[Iru Cai]

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()?"

And the machine cannot boot.

Has anyone seen this issue before?

Thanks,
Iru
