The main purpose of this patch is to separate a generic interface for updating firmware using DFU drivers from "auto-update" via tftp.
This function will also be used in implementing UEFI capsule update in a later commit.

With patch
cmd: drop fitupd command https://patchwork.ozlabs.org/project/uboot/patch/20200617090903.9268-1-xypro...
the fitupd command is removed.
Lukasz has to put the patch into a pull request, yet
Once that patch has been inserted only the automatic fit updates will use code in common/update.c. This code is not called by the 'dfu tftp' command.
The function fit_update() that you create should be considered a part of the dfu framework and should be placed in drivers/dfu/dfu.c. Please, give it a name starting with dfu_.
This way there is no need to change the Kconfig for common/update.c as update.c remains dedicated to automatic updates via tFTP.
Best regards
