I see that you have added these three new device IDs:

{0x8086, 0xa1c8, NT,  "Intel", "C620 Series Chipset Supersku",
enable_flash_c620},
{0x8086, 0xa248, NT,  "Intel", "C620 Series Chipset Supersku",
enable_flash_c620},
{0x8086, 0xa249, NT,  "Intel", "C620 Series Chipset Supersku",
enable_flash_c620},

I can confirm that the last two IDs are for Super SKUs, but "0xa1c8"
(the first one) seems to be a "QS/PRQ" SKU. Could you please confirm
it? I have created a change to add these IDs:

https://review.coreboot.org/39780

In addition, since flashrom can successfully update the BIOS on these
chipsets, knowing the Device IDs that have been tested would be much
appreciated. That way, we can mark the chipsets as tested.

The Arduino-based programmers are more complicated to debug and use,
primarily because the Arduino works at 5V while the flash chips run
with at most 3.3V. In your case, the datasheet says so:

https://www.winbond.com/resource-files/w25x10cl_revg%20021714.pdf

Are you following any particular guide? To avoid damaging the flash
chip, one should use a level shifter. The flashrom wiki page has some
information:

Hello all. It seems that I am having issues with my Arduino based flasher.
I installed Frser-duino on my Arduino UNO and tried flashing a
winbond 25x10cln1g. However I am running into errors. My log is here:
https://pastebin.com/eLJNu43T I would greatly appreciate any help.

Hi David:

For flashrom could update BIOS successfully on the Intel Bakerville
platform(CPU:SKY-D), we need to add device id to chipset_enables table in
the file of"chipset_enables.c", or it will cause below error:
WARNING: No chipset found. Flash detection will most likely fail.
No EEPROM/flash device found.
Note: flashrom can never write if the flash chip isn't found automatically.

So could you please help to add these three device ids to the
chipset_enable table and upload to the Github?
Attached the changed file.

Thanks,
Best Regards,
Ocean
