From a7a19b1c19a3c27cf96adb1e3eaf35d48e0a1f6a Mon Sep 17 00:00:00 2001 From: Michael Walle Date: Fri, 5 Jun 2020 00:11:22 +0200 Subject: [PATCH] configs/kontron_smarc_sal28: new defconfig Now that upstream supports this board add buildroot support for it, too. This supports: - latest upstream linux kernel. Since the support for this board and its SoC is still in active development, we want to follow the upstream kernel releases for now. - building an image which can be installed to eMMC, SD card or USB thumb drive. - upstream u-boot patches are pending, therefore no support for building a bootloader for now.
