Subject: [PATCHv2 6/6] mtd/denali: support for cmdline partitioning
Date: Fri,  3 Jun 2011 11:32:49 +0100	[thread overview]
Message-ID: <1307097169-11744-7-git-send-email-jamie@jamieiles.com> (raw)
In-Reply-To: <1307097169-11744-1-git-send-email-jamie@jamieiles.com>

Add support for command line partitioning.  This is favoured over
platform data based partitions.
