Subject: [PATCH] board: sama5d27_som1_ek: Get dram size and base from device
 tree
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

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.
