[PATCH 03/21] hw/arm/collie: Create the RAM in the board


From: Philippe Mathieu-Daudé
Subject: [PATCH 03/21] hw/arm/collie: Create the RAM in the board
Date: Mon, 21 Oct 2019 00:56:32 +0200

The SDRAM is incorrectly created in the SA1110 SoC.
Move its creation in the board code, this will later allow the
board to have the QOM ownership of the RAM.
