From mboxrd@z Thu Jan 1 00:00:00 1970 From: Christopher Spinrath Date: Sun, 19 Jun 2016 17:44:56 +0200 Subject: [U-Boot] [PATCH 3/3] ARM: configs: cm_fx6: add mtd support In-Reply-To: <20160619154456.29027-1-christopher.spinrath@rwth-aachen.de> References: <20160619154456.29027-1-christopher.spinrath@rwth-aachen.de> Message-ID: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de The cm-fx6 module has an on-board spi flash chip. Enable mtd support and the mtdparts command. Also define a default partitioning, add it to the default environment, and enable support to overwrite the partitioning defined in a device tree by it. These changes move the effective default partitioning from the device tree shipped with the vendor kernels to u-boot which becomes the single point of definition for the partitioning for all device tree based kernels (in particular, for the upstream linux kernel which does not have a default partitioning defined in its device tree).
