Subject: [PATCH 2/2] m25p80: use proper erasesize for SECT_4K devices
Date: Thu, 15 Sep 2011 15:31:45 +0400 [thread overview]
Message-ID: <3e59cfc265c6623c3a5c6013991ed667111fc1df.1316086518.git.fercerpav@gmail.com> (raw)
In-Reply-To: <560194a56016e7562eb1e50f68a58ff6f6e069a7.1316086518.git.fercerpav@gmail.com>
This fixes a bug that causes only the first 4K out of every 64K to be
erased on SECT_4K devices.
