  1. JFFS2 NAND support:
  2. To enable, use the following #define in the board configuration file:
  3. #define CONFIG_JFFS2_NAND 1
  4. Configuration of partitions is similar to how this is done in U-Boot
  5. for JFFS2 on top NOR flash. If a single partition is used, it can be
  6. configured using the following #defines in the configuration file:
  7. #define CONFIG_JFFS2_NAND_DEV 0 /* nand device jffs2 lives on */
  8. #define CONFIG_JFFS2_NAND_OFF 0 /* start of jffs2 partition */
  9. #define CONFIG_JFFS2_NAND_SIZE 2*1024*1024 /* size of jffs2 partition */
  10. If more than a single partition is desired, the user can define a
  11. CONFIG_SYS_JFFS_CUSTOM_PART macro and implement a
  12. struct part_info* jffs2_part_info(int part_num)
  13. function in a board-specific module. An example of such function is
  14. available in common/cmd_jffs2.c
  15. The default configuration for the DAVE board has a single JFFS2
  16. partition of 2 MB size.
