- Note: CONFIG_ENV_OFFSET and CONFIG_ENV_OFFSET_REDUND must be aligned

- the NAND devices block size.
+ - CONFIG_ENV_RANGE (optional):
+
+ Specifies the length of the region in which the environment
+ can be written. This should be a multiple of the NAND device's
+ block size. Specifying a range with more erase blocks than
+ are needed to hold CONFIG_ENV_SIZE allows bad blocks within
+ the range to be avoided.

+
+ Enables support for dynamically retrieving the offset of the
+ environment from block zero's out-of-band data. The
+ "nand env.oob" command can be used to record this offset.
+ Currently, CONFIG_ENV_OFFSET_REDUND is not supported when
+ using CONFIG_ENV_OFFSET_OOB.

+LED display internal API
+=======================================
+
+This README describes the LED display API.
+
+The API is defined by the include file include/led-display.h
+
+The first step in to define CONFIG_CMD_DISPLAY in the board config file.
+Then you need to provide the following functions to access LED display:
+
+void display_set(int cmd);
+
+This function should control the state of the LED display. Argument is
+an ORed combination of the following values:
+ DISPLAY_CLEAR -- clear the display
+ DISPLAY_HOME -- set the position to the beginning of display
+ DISPLAY_MARK -- enable mark (decimal point), if implemented
+
+int display_putc(char c);
+
+This function should display it's parameter on the LED display in the
+current position. Returns the displayed character on success or -1 in
+case of failure.
+
+With this functions defined 'display' command will display it's
+arguments on the LED display (or clear the display if called without
+arguments).
