possible to transfer FIT images with firmware updates via TFTP and use
DFU backend for storing them.

+Device Firmware Upgrade (DFU) - extension to use TFTP
+=====================================================
+
+Why?
+----
+
+* Update TFTP (CONFIG_UPDATE_TFTP) only supports writing
+code to NAND memory via TFTP.
+* DFU supports writing data to the variety of mediums (NAND,
+eMMC, SD, partitions, RAM, etc) via USB.
+
+Combination of both solves their shortcomings!
+
+
+Overview
+--------
+
+This document briefly describes how to use DFU for
+upgrading firmware (e.g. kernel, u-boot, rootfs, etc.)
+via TFTP protocol.
+
+By using Ethernet (TFTP protocol to be precise) it was
+possible to overcome the major problem of USB based DFU -
+the relatively low transfer speed for large files.
+This was caused by DFU standard, which imposed utilization
+of only EP0 for transfer. By using Ethernet we can circumvent
+this shortcoming.
+
+Beagle Bone Black (BBB) powered by TI's am335x CPU has been used
+as a demo board.
+
+To utilize this feature, one needs to first enable support
+for USB based DFU (CONFIG_DFU_*) and DFU TFTP update
+(CONFIG_DFU_TFTP) described in ./doc/README.update.
+
+The "dfu" command has been extended to support transfer via TFTP - one
+needs to type for example "dfu tftp 0 mmc 0"
+
+This code works without "fitupd" command enabled.
+
+As of this writing (SHA1:241746e618fa725491e9ff689710c5f73ffd9139) the
+update.c code is not enabled (CONFIG_UPDATE_TFTP) by any board in the
+contemporary u-boot tree.
+
+
+Environment variables
+---------------------
+
+The "dfu tftp" command can be used in the "preboot" environment variable
+(when it is enabled by defining CONFIG_PREBOOT).
+This is the preferable way of using this command in the early boot stage
+as the opposition to legacy update_tftp() function invoking.
+
+
+Beagle Bone Black (BBB) setup
+-----------------------------
+
+1. Setup tftp env variables:
+ * select desired eth device - 'ethact' variable ["ethact=cpsw"]
+ (use "bdinfo" to check current setting)
+ * setup "serverip" and "ipaddr" variables
+ * set "loadaddr" as a fixed buffer where incoming data is placed
+ ["loadaddr=0x81000000"]
+
+#########
+# BONUS #
+#########
+It is possible to use USB interface to emulate ETH connection by setting
+"ethact=usb_ether". In this way one can have very fast DFU transfer via USB.
+
+For 33MiB test image the transfer rate was 1MiB/s
+
+2. Setup update_tftp variables:
+ * set "updatefile" - the file name to be downloaded via TFTP (stored on
+ the HOST at e.g. /srv/tftp)
+
+3. If required, to update firmware on boot, put the "dfu tftp 0 mmc 0" in the
+ "preboot" env variable. Otherwise use this command from u-boot prompt.
+
+4. Inspect "dfu" specific variables:
+ * "dfu_alt_info" - information about available DFU entities
+ * "dfu_bufsiz" - variable to set buffer size [in bytes] - when it is not
+ possible to set large enough default buffer (8 MiB @ BBB)
+
+
+
+FIT image format for download
+-----------------------------
+
+To create FIT image for download one should follow the update tftp README file
+(./doc/README.update) with one notable difference:
+
+The original snippet of ./doc/uImage.FIT/update_uboot.its
+
+ images {
+ update at 1 {
+ description = "U-Boot binary";
+
+should look like
+
+ images {
+ u-boot.bin at 1 {
+ description = "U-Boot binary";
+
+where "u-boot.bin" is the DFU entity name to be stored.
+
+
+
+To do
+-----
+
+* Extend dfu-util command to support TFTP based transfers
+* Upload support (via TFTP)

This change gives the ability to reuse the <tftp.h> header file by other
subsystems (like e.g. dfu).
Without this change compilation error emerges for the legacy update.c file.

Up till now it was impossible to use code from update.c when system
was not equipped with raw FLASH memory.
Such behavior prevented DFU from reusing this code.

This function allows writing via DFU data stored from fixed buffer address
(like e.g. loadaddr env variable).
Such predefined buffers are used in the update_tftp() code. In fact this
function is a wrapper on the dfu_write() and dfu_flush().

This code allows using DFU defined mediums for storing data received via
TFTP protocol.
It reuses and preserves functionality of legacy code at common/update.c.
The update_tftp() function now accepts parameters - namely medium device
name and its number (e.g. mmc 1).
Without this information passed old behavior is preserved.

Changes for v2:
- Remove env variables from update_tftp() function
- Add parameters to update_tftp() function - without them old behavior is
preserved
- Stop compilation when legacy flags (CONFIG_UPDATE_TFTP and CONFIG_SYS_NO_FLASH)
are wrongly defined
- In the u-boot code legacy calls to update_tftp(0UL) have been changed to
update_tftp(0UL, NULL, NULL)
Changes for v3:
- Add proper update_tftp() function description in the ./include/net.h file

The "dfu" command has been extended to support transfers via TFTP protocol.

Changes for v2:
- Remove "dfutftp" command
- Modify "dfu" command to support optional [tftp] parameter
- Only one flag (CONFIG_DFU_TFTP) needs to be enabled
Changes for v3:
- Remove #ifdef CONFIG_DFU_TFTP to guard including <net.h>
- Do not use usb_controller variable in the 'dfu tftp' case
- Make the tftp as the explicit parameter for the 'dfu tftp' command
- Correct help message for 'dfu tftp' command

This is a pretty verbose bool text. The help is there for
clarification and wordiness. Maybe something like "DFU via TFTP".

This looks like you simply added this option to the end of the list.
You should run this through "make savedefconfig" so we don't generate
churn on future config changes.

Yes, exactly.

Please correct me if I'm wrong. I should run make savedefconfig on the
proper .config. Then mv defconfig ./configs/am335x_boneblack_defconfig
and commit changes?

You should add it (as you did is fine), then run 'make
am335x_boneblack_defconfig', then run 'make savedefconfig', then 'mv
defconfig configs/am335x_boneblack_defconfig'. I think this is the
process you were describing but I wanted to be explicit.
