Subject: [U-Boot] [PATCH 09/12] rockchip: ram: add dm-based sdram driver
Date: Fri, 25 Oct 2019 01:28:00 +0200 [thread overview]
Message-ID: <20191024232803.10338-10-heiko@sntech.de> (raw)
In-Reply-To: <20191024232803.10338-1-heiko@sntech.de>
From: Heiko Stuebner <heiko.stuebner@theobroma-systems.com>
sdram configuration happens outside of dm-infrastructure in special
tpl-code, so the sdram driver itself has just the function to read
back the sdram configuration and allow main uboot to handle dram sizes.
