@ -1344,6 +1344,29 @@ The following options need to be configured:
CONFIG_SH_MMCIF_CLK
Define the clock frequency for MMCIF
- USB Device Firmware Update (DFU) class support:
CONFIG_DFU_FUNCTION
This enables the USB portion of the DFU USB class
CONFIG_CMD_DFU
This enables the command "dfu" which is used to have
U-Boot create a DFU class device via USB. This command
requires that the "dfu_alt_info" environment variable be
set and define the alt settings to expose to the host.
CONFIG_DFU_MMC
This enables support for exposing (e)MMC devices via DFU.
CONFIG_DFU_NAND
This enables support for exposing NAND devices via DFU.
CONFIG_SYS_DFU_MAX_FILE_SIZE
When updating files rather than the raw storage device,
we use a static buffer to copy the file into and then write
the buffer once we've been given the whole file. Define
this to the maximum filesize (in bytes) for the buffer.
Default is 4 MiB if undefined.
- Journaling Flash filesystem support:
CONFIG_JFFS2_NAND, CONFIG_JFFS2_NAND_OFF, CONFIG_JFFS2_NAND_SIZE,
CONFIG_JFFS2_NAND_DEV
