[PATCH 1/3] mtd: abi: Introduce MTD_NO_MULTI_PASS_WRITE

From: Pratyush Yadav
Date: Mon Oct 12 2020 - 14:04:34 EST


Some flashes like the Semper S28 family do not support multi-pass page
programming. Introduce the flag MTD_NO_MULTI_PASS_WRITE to allow telling
upper layers this information so they can issue write commands with this
limitation in mind.
