[PATCH 08/28] mtd: spinand: Decouple write enable and write disable operations

Fri Oct 31 10:26:52 PDT 2025


In order to introduce templates for all operations and not only for page
helpers (in order to introduce octal DDR support), decouple the WR_EN
and WR_DIS operations into two separate macros.

Adapt the callers accordingly.

There is no functional change.
