-This patch series adds support for ext4 ls,load and write features in uboot
-Journaling is supported for write feature.
-
-To enable support for the ext4 (and ext2) filesystem implementation,
-#define CONFIG_FS_EXT4
-
-If you want write support,
-#define CONFIG_EXT4_WRITE
-
-To Enable ext2 ls and load commands, modify the board specific config file with
-#define CONFIG_CMD_EXT2
-This automatically defines CONFIG_FS_EXT4 for you.
-
-To Enable ext4 ls and load commands, modify the board specific config file with
-#define CONFIG_CMD_EXT4
-This automatically defines CONFIG_FS_EXT4 for you.
-
-To enable ext4 write command, modify the board specific config file with
-#define CONFIG_CMD_EXT4
-#define CONFIG_CMD_EXT4_WRITE
-These automatically define CONFIG_FS_EXT4 and CONFIG_EXT4_WRITE for you.
-
-Also relevant are the generic filesystem commands,
-#define CONFIG_CMD_FS_GENERIC
-This does not automatically enable EXT4 support for you.
-
-Steps to test:
-
-1. After applying the patch, ext4 specific commands can be seen
- in the boot loader prompt using
- UBOOT #help
-
- ext4load- load binary file from a Ext4 file system
- ext4ls - list files in a directory (default /)
- ext4write- create a file in ext4 formatted partition
-
-2. To list the files in ext4 formatted partition, execute
- ext4ls <interface> <dev[:part]> [directory]
- For example:
- UBOOT #ext4ls mmc 0:5 /usr/lib
-
-3. To read and load a file from an ext4 formatted partition to RAM, execute
- ext4load <interface> <dev[:part]> [addr] [filename] [bytes]
- For example:
- UBOOT #ext4load mmc 2:2 0x30007fc0 uImage
-
-4. To write a file to a ext4 formatted partition.
- a) First load a file to RAM at a particular address for example 0x30007fc0.
- Now execute ext4write command
- ext4write <interface> <dev[:part]> [filename] [Address] [sizebytes]
- For example:
- UBOOT #ext4write mmc 2:2 /boot/uImage 0x30007fc0 6183120
- (here 6183120 is the size of the file to be written)
- Note: Absolute path is required for the file to be written
