That function should drop. There is not other architecture that does it. What about:
I implemented your suggestion like this:
--- a/arch/arm/mach-imx/imx8m/soc.c +++ b/arch/arm/mach-imx/imx8m/soc.c @@ -1536,6 +1536,14 @@ enum env_location arch_env_get_location(enum env_operation op, int prio) return ENVL_UNKNOWN;
switch (dev) { + case USB_BOOT: + if (IS_ENABLED(CONFIG_ENV_IS_IN_SPI_FLASH)) + return ENVL_SPI_FLASH; + if (IS_ENABLED(CONFIG_ENV_IS_IN_NAND)) + return ENVL_NAND; + if (IS_ENABLED(CONFIG_ENV_IS_IN_MMC)) + return ENVL_MMC; + return ENVL_NOWHERE; case QSPI_BOOT: case SPI_NOR_BOOT: if (IS_ENABLED(CONFIG_ENV_IS_IN_SPI_FLASH))
This still allows me to save the env into the eMMC when U-Boot is loaded from USB.
register_enviroment_hook() deregister_enviroment_hook()
This can replace the one default with board/arch etc

Is this the mechanism that you are looking for?
