> Yes, the Flash density is 64MB

Not sure if you can access https://chromium-review.googlesource.com/c/chromiumos/third_party/flashrom/+.... We don't plan to use 64MB flash out hence, we might need to fake this part to show the max capacity is 32MB. Flashing 64MB takes significantly higher time.

this is must for the ChromeOS device hence, asked to specify those details.
