[U-Boot] [RFC PATCH 00/14] dfu: update dfu stack and use them for stm32mp1

[Lukasz Majewski]

Hi Patrick,

> 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.

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) ?
