> Subrata can you take a look too please.

There aren't that many systems with 2 flash chips, but they exist. Ivy Bridge and Haswell ThinkPads have a 8 MiB chip and a 4 MiB chip, and flashrom detects a single 12 MiB opaque flash chip. The problem with sending WP commands in such situations is that you have 2 chips to deal with. No idea how hwseq handles this.
