From mboxrd@z Thu Jan 1 00:00:00 1970 From: Philipp Tomsich Date: Mon, 11 Sep 2017 13:59:07 +0200 Subject: [U-Boot] [PATCH 07/10] rockchip: puma-rk3399: update board_init() In-Reply-To: <1505131150-39480-1-git-send-email-philipp.tomsich@theobroma-systems.com> References: <1505131150-39480-1-git-send-email-philipp.tomsich@theobroma-systems.com> Message-ID: <1505131150-39480-8-git-send-email-philipp.tomsich@theobroma-systems.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de The original initialisation code for board_init() was largely lifted from the code on the EVB. However, the RK3399-Q7 can do with a much more concise init sequence. This cleans up the board_init() by updating it to the essentials for the RK3399-Q7 and getting rid of the accumulated cruft.
