We're going to send a similar patch for the Linux kernel as well.
But we're discussing U-Boot here so what is a relationship between
patches here and there?

Please note what Eugeniy answered to your comment  [1]-
if sst26xxx ICs are used in read-only mode or some earlier
stage disabled write lock for entire IC mentioned patch is not
required. But in case of default state of those ICs we do
need to allow writes to certain regions of the flash ICs.
