From 2c01eeece96ce449163e066566c787bfc2a10651 Mon Sep 17 00:00:00 2001 From: Stephane Viau Date: Wed, 27 May 2020 07:07:48 +0200 Subject: [PATCH] configs/freescale_imx8mnevk: new defconfig This patch adds support for the i.MX8M Nano EVK Board [1]. The final boot image is created from uboot and firmware binaries in post image script board/freescale/common/imx/imx8-bootloader-prepare.sh Note that this config is based on 4.19.35_1.1.0 ; hence, the kernel configuration needs host-openssl to build.
