Subject: [PATCH v2 25/48] ARM: i.MX: xload-esdhc: Allow custom buffer address, device offset
Date: Sat, 26 May 2018 13:44:28 -0700	[thread overview]
Message-ID: <20180526204451.16530-26-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20180526204451.16530-1-andrew.smirnov@gmail.com>

Add code to support specifying different buffer address and SD/MMC
device offset to read it from in esdhc_start_image(). This change is
needed to support i.MX8.
