From b1f9ffbfda07acee9bdbc77416facf606647b523 Mon Sep 17 00:00:00 2001 From: Miquel Raynal Date: Thu, 12 Jan 2023 10:36:36 +0100 Subject: mtd: rawnand: Prepare the late addition of supported operation checks Add an empty envelope just to show how to add additional checks for new operations. This is going to be used for sequential cached reads, which require the page size to be known (and the discovery to be over), hence the "late" designation.
