JFFS2 NAND support:

  To enable, use the following #define in the board configuration file:

  
  #define CONFIG_JFFS2_NAND 1
  
  Configuration of partitions is similar to how this is done in  U-Boot

  for  JFFS2  on top NOR flash. If a single partition is used, it can be

  configured using the following #defines in the configuration file:
  
  #define CONFIG_JFFS2_NAND_DEV 0			/* nand device jffs2 lives on */
  #define CONFIG_JFFS2_NAND_OFF 0			/* start of jffs2 partition */
  #define CONFIG_JFFS2_NAND_SIZE 2*1024*1024	/* size of jffs2 partition */
  
  If more than a single partition is desired, the user can define a

  CONFIG_SYS_JFFS_CUSTOM_PART macro and implement a

  
  	struct part_info* jffs2_part_info(int part_num)
  
  function in a board-specific module. An example of such function is
  available in common/cmd_jffs2.c
  
  The default configuration for the DAVE board has a single JFFS2
  partition of 2 MB size.
