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

[Patrick Delaunay]

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.



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
