Subject: [PATCH v2 2/6] ARM: stm32mp: dk2: add barebox SD-Card update handler
Date: Mon, 28 Oct 2019 22:39:39 +0100 [thread overview]
Message-ID: <20191028213943.32071-3-ahmad@a3f.at> (raw)
In-Reply-To: <20191028213943.32071-1-ahmad@a3f.at>
From: Ahmad Fatoum <a.fatoum@pengutronix.de>
Now with the SD/MMC controller supported, lets add a bbu handler, so we
can use it to update the second stage boot loader partition.
