From f3359e50de810d506670f2efd7d6adc802e69876 Mon Sep 17 00:00:00 2001 From: Edward O'Callaghan Date: Fri, 3 May 2019 02:27:24 -0400 Subject: Add support for Adesto AT25SF128A The following adds support for the Adesto AT25SF128A-SHB-T part. We have varied the correct chip name is reported as well as write and read 16MBytes of random data and verified the checksum's match. Further, --wp-list appears to report the correct ranges. BUG=None BRANCH=none TEST=Ran flashrom with a Dediprog SF100, RW random data and checksum matched.

The `.wp` field has also been removed.
