Subject: [PATCH v2 1/5] board: sama5d27_som1_ek: Get dram size and base from device tree
Date: Mon, 16 Aug 2021 14:25:39 +0200	[thread overview]
Message-ID: <20210816122543.33532-2-clement.leger@bootlin.com> (raw)
In-Reply-To: <20210816122543.33532-1-clement.leger@bootlin.com>

In order to make it more flexible and allow modifying the base address
of DRAM without recompiling U-Boot, use memory node from device tree
with fdtdec functions.
