JFFS2 NAND support:
 | 
			
		||||
 | 
			
		||||
To ebable, 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 parition 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
 | 
			
		||||
CFG_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.
