+Saving environment
+------------------
+
+SAVEENV is disabled by default and for the new flow uses Uenv.txt as the default
+way for saving the environments. This has been done as Uenv.txt is more granular
+then the saveenv command and can be used across various bootmodes too.

+
+.. code-block::
+
+  => env export -t $loadaddr <list of variables>
+  => fatwrite mmc ${mmcdev} ${loadaddr} ${bootenvfile} ${filesize}
+
+**Reading from MMC/EMMC**
+
+By default run envboot will read it from the MMC/EMMC partition ( based on
+mmcdev) and set the environments.
+
+If manually needs to be done then the environment can be read from the
+filesystem and then imported

+.. code-block::
+
+  => fatload mmc ${mmcdev} ${loadaddr} ${bootenvfile}
+  => env import -t ${loadaddr} ${filesize}
