Hello Peter,
-----Original Message----- From: Peter Bergin peter@berginkonsult.se Sent: Sunday, February 14, 2021 8:19 PM To: u-boot@lists.denx.de Cc: Peter Bergin peter@berginkonsult.se; ZHIZHIKIN Andrey andrey.zhizhikin@leica-geosystems.com Subject: [PATCH v2] doc: board: freescale: imx8mp_evk: update to newer versions and change ATF_LOAD_ADDR
Update imx-atf and firmware-imx to latest released versions.
Update address of ATF_LOAD_ADDR that has changed to 0x970000 in imx-atf commit 48733cb4e773a7584ced601de9d717efa3d73815.
Add 'O=' to make and build in separate directory as one issue has been noticed where it was trouble building directly inside u-boot source dir. Restructure the workflow and copy binaries after defconfig to ensure that build directory is created.
