+

+

+
+	- CONFIG_ENV_OFFSET:
+	- CONFIG_ENV_SIZE:
+
+	  These two #defines specify the offset and size of the environment
+	  area within the specified MMC device.
+
+	  If offset is positive (the usual case), it is treated as relative to
+	  the start of the MMC partition. If offset is negative, it is treated
+	  as relative to the end of the MMC partition. This can be useful if
+	  your board may be fitted with different MMC devices, which have
+	  different sizes for the MMC partitions, and you always want the
+	  environment placed at the very end of the partition, to leave the
+	  maximum possible space before it, to store other data.

+	- CONFIG_ENV_OFFSET_REDUND (optional):
+
+	  Specifies a second storage area, of CONFIG_ENV_SIZE size, used to
+	  hold a redundant copy of the environment data. This provides a
+	  valid backup copy in case the other copy is corrupted, e.g. due
+	  to a power failure during a "saveenv" operation.
+
+	  This value may also be positive or negative; this is handled in the
+	  same way as CONFIG_ENV_OFFSET.
