This serie based on v2019.07 propose some update on the DFU stack:
- add capability to have several DFU backend running in parallel
- add MTD backend for NAND, NOR or SPI-NAND
- add VIRTUAL backend for board/command specific behavior
- add some weak callback
To test the feature and as example, I update the stm32mp1
to use the new features (tested with command "dfu 0")
This serie prepares the DFU backend for communication with
STM32CubeProgrammer on stm32mp1 platform (stm32prog command).
This STMicroelectronics tool is based on DFU protocol and
update the boot devices and the OTPs on the ST boards.

Copy the partition support from NAND backend to SF,
support part and partubi option.
In case of ubi partition, erase the rest of the
partition as it is mandatory for UBI.
for example:
U-Boot> env set dfu_alt_info "spl part 0 1;\
u-boot part 0 2;u-boot-env part 0 3;UBI partubi 0 4"
U-Boot> dfu 0 sf 0:0:10000000:0

Add support of DFU for several interface/device
with one command.
The format for "dfu_alt_info" in this case is :
interface with devstring'='alternate list (';' separated)
and each interface is separated by '&'
The previous behavior is always supported.
One example for NOR (bootloaders) + NAND (rootfs in UBI):
U-Boot> env set dfu_alt_info \
"sf 0:0:10000000:0=spl part 0 1;u-boot part 0 2; \
u-boot-env part 0 3&nand 0=UBI partubi 0,3"
U-Boot> dfu 0 list
DFU alt settings list:
dev: SF alt: 0 name: spl layout: RAW_ADDR
dev: SF alt: 1 name: ssbl layout: RAW_ADDR
dev: SF alt: 2 name: u-boot-env layout: RAW_ADDR
dev: NAND alt: 3 name: UBI layout: RAW_ADDR
U-Boot> dfu 0
$> dfu-util -l

This patch allows into the DFU backend to indicate that there is no
remaining data (for EOF for example). That allows users to read a
buffer greater than the device size; the dfu stack stops the read
request when the backend return a length=0 without error.

Add DFU backend for MTD device: allow to read
and write on any MTD device (RAW or SPI)
For example :
> set dfu_alt_info "nand_raw raw 0x0 0x100000"
> dfu 0 mtd nand0
This MTD backend provides the same level than dfu nand
backend for NAND in RAW mode and sf backend for NOR;
So it can replace booth of them but it can also
add support of spi-nand.
> set dfu_alt_info "nand_raw raw 0x0 0x100000"
> dfu 0 mtd spi-nand0
The backend code is based on the MTD command
introduced by commit 5db66b3aee6f ("cmd: mtd:
add 'mtd' command")

Add the support of MTD partition for the MTD backend.
The expected dfu_alt_info for one alternate on the mtd device :
<name> part <part_id>
<name> partubi <part_id>
"partubi" also erase up to the end of the partition after write operation.
For example: dfu_alt_info = "spl part 1;u-boot part 2; UBI partubi 3"
U-Boot> dfu 0 mtd nand0

Add weak callback to allow board specific behavior
- flush
- initiated
This patch prepare usage of DFU back end for communication with
STM32CubeProgrammer on stm32mp1 platform with stm32prog command.

Generate automatically dfu_alt_info for the supported device.
The simple command "dfu 0" allows to start the dfu stack on usb 0
for the supported devices:
- dfu mtd for nand0
- dfu mtd for nor0
- dfu mmc for SDCard
- dfu mmc for eMMC
- dfu ram for images in DDR
The DUF alternate use the "part", "partubi" and "mmcpart" options
to select the correct MTD or GPT partition or the eMMC hw boot partition.

I'm aware that the dfu.c file in some places uses -1 or -<errno> as
return value.
I would prefer that with new code we shall add -<errno>. In this
particular case it would be -ENOMEM

Please add this info (with above example usage) to ./doc/README.dfu (in
a similar way as I did it some time ago for ./doc/README.dfutftp).
I also think that it would be beneficial for the community to add a
separate entry (in this file) for the description of ST's way to
program their platform with this code.
(I mean simple howto for people who would like to start playing around
with ST & U-Boot & DFU).

Hi Patrick,
> Add DFU backend for MTD device: allow to read
> and write on any MTD device (RAW or SPI)
>
> For example :
> > set dfu_alt_info "nand_raw raw 0x0 0x100000"
> > dfu 0 mtd nand0
>
> This MTD backend provides the same level than dfu nand
> backend for NAND in RAW mode and sf backend for NOR;
> So it can replace booth of them but it can also
> add support of spi-nand.
>
> > set dfu_alt_info "nand_raw raw 0x0 0x100000"
> > dfu 0 mtd spi-nand0
>
> The backend code is based on the MTD command
> introduced by commit 5db66b3aee6f ("cmd: mtd:
> add 'mtd' command")
Please also add documentation entry for this feature/extension.

Hi Patrick,

This looks like a great enhancement. Please add detailed documentation
entry of its intended usage.

Hi Patrick,
> Add weak callback to allow board specific behavior
> - flush
> - initiated
>
> This patch prepare usage of DFU back end for communication with
> STM32CubeProgrammer on stm32mp1 platform with stm32prog command.
Would the stm32prog need to modify the environment variables ?
For example to update the "VERSION" or any other one?

Thanks for such great enhancement on DFU. I've added Heiko to CC, so he
also would be aware of your work (as some of his boards use DFU for
update).
Please add detailed documentation entry (as I've indicated in other
patches reviewed) for above features.
The roadmap:
- Please send v1 (without RFC). (Please run buildman on several siemens
and trats/trats2/odroid-x* boards)
- I will test it on odroid-XU3 (and probably Heiko would test it for
regression).
A side question - would you need in some point updating envs via DFU
(no matter if those would be a whole image created with mkimage or an
individual one) ?
