Subject: [PATCH v2 06/17] drivers:mtd:ubi:add bakvol function define in ubi layer
Date: Tue, 2 Feb 2016 02:30:41 +0000 [thread overview]
Message-ID: <1454380252-16170-7-git-send-email-jackyard88@gmail.com> (raw)
In-Reply-To: <1454380252-16170-1-git-send-email-jackyard88@gmail.com>
From: Bean Huo <beanhuo@micron.com>
This file patch is to add bakvol function define in ubi layer and
add bakvol point in ubi_device structure. Add one new parameter for ubi layer write
function, in order to indicate if this time programming data should be protected.
