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
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.
