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).
Changes in v2: - Add dfu documentation - Update dfu documentation for callbacks - Add dfu documentation for several device - Update commit message - Update commit message - Update dfu documentation for MTD - Update dfu documentation for MTD - Update dfu documentation for virtual backend - Update dfu documentation for callbacks - Update callbacks comment after Lukasz review - Update after Lukasz Majewski comments
