From bff5ae49ec69efd960f839ff24709f329f08dab8 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Wed, 7 Aug 2019 16:24:56 +0200 Subject: [PATCH] configs/stm32mp157_dk: new defconfig This commit adds a minimal defconfig to build a Buildroot system for the STM32MP157 Discovery Kit, which is the low-cost evaluation platform for the new STM32MP157 system-on-chip from ST. This system-on-chip features a single or dual Cortex-A7, a single Cortex-M4, and a wide variety of peripherals. This commit includes a custom linux configuration file, because there is no specific defconfig for this platform in the kernel, only multi_v7_defconfig supports it, which is really a massive defconfig. That's why a custom linux configuration file is added. A small U-Boot config fragment allows to disable the watchdog, so that userspace by default doesn't need to have a watchdog daemon running. The vendor U-Boot and Linux trees are used for the moment, but the platform support is being upstreamed, so switching to upstream versions will be possible in the relatively near future.
