From a20dbbb0711ef144703848105dd0500b16ba7eae Mon Sep 17 00:00:00 2001 From: =?utf8?q?Jo=C3=A3o=20Paulo=20Gon=C3=A7alves?= Date: Mon, 11 Aug 2025 09:57:50 -0300 Subject: [PATCH] arm: imx: imx9: soc: Fix env location when booting from USB MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit On i.MX9 platforms, when booting from USB, the U-Boot environment is always assumed to be in RAM. However, this causes the boot to hang when `CONFIG_ENV_IS_NOWHERE` is not enabled. The boot also hangs even if the environment is present in another storage media (for example, eMMC). Fix the issue by correctly handling the U-Boot environment's location when booting from USB. Also for i.MX95, set the environment location based on the ENV config and not solely based on the boot device type.
