From mboxrd@z Thu Jan 1 00:00:00 1970 From: Giulio Benetti Date: Fri, 19 Feb 2021 00:26:19 +0100 Subject: [PATCH 4/5] sun7i: add support for Micronova srl s027_3 board In-Reply-To: <20210218232622.883509-1-giulio.benetti@benettiengineering.com> References: <20210218232622.883509-1-giulio.benetti@benettiengineering.com> Message-ID: <20210218232622.883509-5-giulio.benetti@benettiengineering.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de From: Giulio Benetti Add support for Micronova srl s027_3 board by adding new vendor/board folders and using in local Makefile the already present board/sunxi/Makefile. The reason is that s027_3 needs a pin to be asserted to enable lcd before setting controller up and sunxi board doesn't provide a way to do this customization.
