From c8e173da6fb02b2fd4c1960757df958b4a3230bf Mon Sep 17 00:00:00 2001 From: Stephane Viau Date: Thu, 25 Mar 2021 07:21:41 +0100 Subject: [PATCH] configs/freescale_imx8mpevk: new defconfig This patch adds support for the NXP i.MX 8M Plus 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. This first support is based on NXP's 5.4.70_2.3.0 BSP.
