[U-Boot] [PATCH 00/14] dfu: update dfu stack and add MTD backend

This serie based on v2019.10-rc3 propose updates on the DFU stack:
- add capability to have several DFU backend running in parallel
- add MTD backend for update of NAND, NOR or SPI-NAND
- add VIRTUAL backend for board/command specific behavior
- add some weak callback

It is the same content that the previous RFC:
http://patchwork.ozlabs.org/project/uboot/list/?series=120375
"dfu: update dfu stack and use them for stm32mp1"

To test the new features and as example, I update the stm32mp1 board
to use the new features; I test them with the command "dfu 0"
(for test I have dependency with patch
 http://patchwork.ozlabs.org/patch/1162076/)

The expected target of the dfu part for this serie is v2020.01.
I will merge the stm32mp1 part when they will be accepted by dfu
maintainers.

This serie prepares the DFU backend for the coming 'stm32prog' command
and for STM32CubeProgrammer on stm32mp1 platform.
This STMicroelectronics tool is based on DFU protocol and allows to
update all the boot devices and the OTPs on the ST boards
(so several DFU target in parallel, including spi nand).



Patrick Delaunay (14):
  dfu: cosmetic: cleanup sf to avoid checkpatch error
  dfu: sf: add partition support for nor backend
  dfu: prepare the support of multiple interface
  dfu: allow to manage DFU on several devices
  dfu: allow read with 0 data for EOF indication
  dfu: add backend for MTD device
  dfu: add partition support for MTD backend
  dfu: add DFU virtual backend
  dfu: add callback for flush and initiated operation
  stm32mp1: activate DFU support and command MTD
  stm32mp1: activate SET_DFU_ALT_INFO
  stp32mp1: configs: activate CONFIG_MTD_SPI_NAND
  stm32mp1: board: add spi nand support
  stm32mp1: add support for virtual partition read
