Subject: [PATCH 2/3] mtd/nand : set correct length to FBCR for a non-full-page write
Date: Thu, 24 Nov 2011 08:41:45 +0800 [thread overview]
Message-ID: <1322095306-13156-2-git-send-email-b35362@freescale.com> (raw)
In-Reply-To: <1322095306-13156-1-git-send-email-b35362@freescale.com>
From: Liu Shuo <b35362@freescale.com>
When we do a non-full-page write, the length be set to FBCR should
not be 'elbc_fcm_ctrl->index', it should be 'elbc_fcm_ctrl->index -
elbc_fcm_ctrl->column'.
