From a702ae7a015fc0944ce5b5cc2d9779c6ba4ca9e4 Mon Sep 17 00:00:00 2001 From: Ye Li Date: Fri, 28 Apr 2023 12:08:36 +0800 Subject: [PATCH] imx9: allow to bootaux Mcore with input address Currently bootaux only supports to boot M33 core from TCM. Since ATF has changed to use x2 parameter for M33 image address, update the bootaux command to use input address, so we can support boot from any possilbe address like TCM, DDR, Flexspi NOR.
