Hi Tom,

Don't want to pester you. I'm just checking on the status regarding this 
patch. Without it the environment is not accessible in the SPL for the 
omap platforms and we rely on the environment for the falcon boot.

A word of warning: this commit may break SPL_ENV_SUPPORT on platforms that
do not register the same MMC controllers in SPL and in u-boot (mostly iMX6
based platforms). Fortunately none of those activate SPL_ENV_SUPPORT in
their default configuration.

[U-Boot] [PATCH] env_mmc: Allow SPL to use any MMC device to load/save the environment

2017-02-01 Thread Jean-Jacques Hiblot 
SPL has been restricted to use only dev 0 based on the assumption that only
one MMC device is registered. This is not always the case and many
platforms now register several devices as expected by the spl mmc boot code
For those platform SPL_ENV_SUPPORT is broken if dev is forced to 0.

A word of warning: this commit may break SPL_ENV_SUPPORT on platforms that
do not register the same MMC controllers in SPL and in u-boot (mostly iMX6
based platforms). Fortunately none of those activate SPL_ENV_SUPPORT in
their default configuration.
