Subject: [PATCH] common/bootargs: add blkdevparts variables
Date: Mon, 16 Feb 2015 14:03:18 +0100 [thread overview]
Message-ID: <1424091798-23393-1-git-send-email-h.feurstein@gmail.com> (raw)
From: Hubert Feurstein <hubert.feurstein@deto.at>
The kernel command line option blkdevparts works like mtdparts, but for all
block devices. So it can be used for eMMC devices without the need of a
traditional partition table.
