From: Jean-Jacques Hiblot Date: Wed, 1 Feb 2017 10:26:53 +0000 (+0100) Subject: env_mmc: Allow SPL to use any MMC device to load/save the environment X-Git-Url: http://git.ipfire.org/?p=people%2Fms%2Fu-boot.git;a=commitdiff_plain;h=687d2073741bf9518247cb3ffb289f428fba2413 env_mmc: Allow SPL to use any MMC device to load/save the environment 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.
