1 JFFS2 options and usage.
2 -----------------------
4 JFFS2 in U-Boot is a read only implementation of the file system in
5 Linux with the same name. To use JFFS2 define CFG_CMD_JFFS2.
7 The module adds three new commands.
8 fsload - load binary file from a file system image
9 fsinfo - print information about file systems
10 ls - list files in a directory
13 There is two ways for JFFS2 to find the disk. The default way uses
14 the flash_info structure to find the start of a JFFS2 disk (called
15 partition in the code) and you can change where the partition is with
19 defined the first flash bank to use
21 CFG_JFFS2_FIRST_SECTOR
22 defines the first sector to use
25 The second way is to define CFG_JFFS_CUSTOM_PART and implement the
26 jffs2_part_info(int part_num) function in your board specific files.
27 In this mode CFG_JFFS2_FIRST_BANK and CFG_JFFS2_FIRST_SECTOR is not
30 The input is a partition number starting with 0.
31 Return a pointer to struct part_info or NULL for error;
33 Ex jffs2_part_info() for one partition.
35 #if defined CFG_JFFS_CUSTOM_PART
36 #include <jffs2/jffs2.h>
38 static struct part_info part;
41 jffs2_part_info(int part_num)
44 if(part.usr_priv==(void*)1)
47 memset(&part, 0, sizeof(part));
48 part.offset=(char*)0xFF800000;
49 part.size=1024*1024*8;
51 /* Mark the struct as ready */
52 part.usr_priv=(void*)1;
63 Add a new command so it's actually possible to change
66 Remove the assumption that JFFS can dereference a pointer
67 into the disk. The current code do not work with memory holes
68 or hardware with a sliding window (PCMCIA).
