Subject: [PATCH 4/5] ARM: stm32mp: dk2: add barebox SD-Card update handler
Date: Mon, 14 Oct 2019 08:39:21 +0200 [thread overview]
Message-ID: <20191014063922.17233-5-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20191014063922.17233-1-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.
