|  | 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 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. |
