2025-08-23arm: imx: imx9: soc: Fix env location when booting from USBJoão Paulo Gonçalves
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.

2025-08-08imx9: soc: Reuse and export low_drive_freq_update()Primoz Fiser
Reuse and export low_drive_freq_update() function. This way global imx9 board_fix_fdt() doesn't duplicate code. While low_drive_freq_update() can be reused on boards such as phyCORE-i.MX93 (TARGET_PHYCORE_IMX93) which is not using the global imx9 board_fix_fdt() implementation. While at it, make printout logic less verbose by only outputting on the error condition and not on each successful clock fixup. Also drop now invalid comment (low_drive_freq_update() now does fixup for internal and kernel device-tree). Signed-off-by: Primoz Fiser <primoz.fiser@norik.com>
2025-06-20env: Rename SYS_MMC_ENV_DEV to ENV_MMC_DEVICE_INDEXMarek Vasut
Rename the variable and add ENV_ prefix, so that all configuration options which are related to environment would have an CONFIG_ENV_ prefix. No functional change. Use ENV_MMC_DEVICE_INDEX to clarify this is the SD/MMC device index, a number, as enumerated by U-Boot. Update the help text accordingly. Signed-off-by: Marek Vasut <marek.vasut+renesas@mailbox.org>

According to iMX93 fuse burn plan, all 9x9 parts will have USB2, ENET1 (FEC), LVDS1, CSI1 and DSI1 disabled. The codes missed ENET1 fuse when detecting 9x9. Although it still can detect 9x9 correctly, we add the ENET1 fuse to the check to be more accurate.

2024-11-09imx9: Improve boot mode autodetectionBenjamin Szőke
Improve "mmcautodetect=yes" boot mode autodetection to able to use it if CONFIG_ENV_IS_NOWHERE=y is used for i.MX9 SoCs and i.MX93 EVK board. If both CONFIG_ENV_IS_IN_MMC=y and CONFIG_ENV_IS_NOWHERE=y are in the defconfig, CONFIG_ENV_IS_IN_MMC=y will be overiden default CONFIG_ENV_IS_NOWHERE settings. Goal is in this patch to able to use the boot mode autodetection if defconfig use only CONFIG_ENV_IS_NOWHERE=y option (without CONFIG_ENV_IS_IN_MMC) for any i.MX9 SoC.

If the PMIC chip has debounce logic for the reset signal, in some corner case the wdog can NOT trigger external PMIC reset if the SoC has been reset internal before the PMIC captures the WDOG_ANY pin reset, so need to keep the WDOG3-5 reset masked in the SRC to let the PMIC to do the reset safely.
