[flashrom] [PATCH] Add support for "ST M25PX16" chip.

[Idwer Vollering]

2010/12/9 Carl Worth <cworth at cworth.org>

> This was created by simply copying the M25PX32 block and verifying
> with the M25PX16 datasheet which values needed to be changed. (The
> only changes are the model_id and the 4 size-related fields).
>
> Also, this commit sets the new M25PX16 as having write support tested,
> (where the M25PX32 does not). This is after running successful write
> and verify operations to 4 different M25PX16 chips with a Dediprog
> SF100.
