From 82810b7b6cc7a74c68881a13b0eb66c7a6370fcc Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Fri, 20 Oct 2006 11:23:56 +0300 Subject: [PATCH] [MTD] NAND: nandsim: support subpage write As flash cannot do 0->1 bit transitions when programming, do not do this in the simulator too. This makes nandsim able to accept subpage writes.
