Subject: [PATCH v4 08/10] ARM: i.MX: bbu: Allow plain i.MX v1 images as a special case
Date: Wed, 27 Jun 2018 21:54:34 -0700 [thread overview]
Message-ID: <20180628045436.16710-9-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20180628045436.16710-1-andrew.smirnov@gmail.com>
If we are passed a plain i.MX v1 image without the usual 1K preamble -
assume a special case and don't try to apply bbu_force() logic.
This is useful in cases where a board specific quirk to make BBU work
is needed.
