Subject: [PATCH] mtd/physmap_of: Don't add disabled flash devices
Date: Tue, 16 Aug 2011 17:25:50 +0800 [thread overview]
Message-ID: <1313486750-15211-1-git-send-email-Chunhe.Lan@freescale.com> (raw)
Flash(cfi-flash, jedec-flash, and so on) nodes with the
property status="disabled" are not usable and so avoid
adding "disabled" flash devices with the system.
