Flashrom on Lenovo V330-14ARR

[murray.calavera]

Hello, I recently ran flashrom on my Lenovo V330-14ARR Laptop and got the following message asking me to make a report:
> $ sudo flashrom -r backup.rom -p internal
> flashrom  on Linux 5.12.19_1 (x86_64)

I have attached the output of lspci -nnvx.
For some context: the vendor firmware on this laptop is likely broken according to linux warning messages and it often fails to boot or even hangs with 100% CPU usage some time after boot. In fact, the reason I am running the 5.12 kernel is because newer kernels hardly boot at all anymore. For this reason I was trying to determine the viability of replacing the vendor firmware with coreboot.

Thank you kindly.
