I think what you're introducing as "CONFIG_DFU_ALT" and renaming "drivers/dfu/dfu_tftp.c" to "drivers/dfu/dfu_alt.c" is what's confusing. That I think needs a different name than "alt" to convey that it's a generic "from DRAM to flash/etc" hook.

The lower impact on the rest of the DFU subsytem and other automated testing that can be done, the easier it can be for someone else to review the DFU parts if Lukasz isn't able to find time to do it. Thanks.

And yes, I'm busy with other work and my time budget is unfortunately reduced since March 2020. It would be good to have some help to not block ongoing DFU development.

This function is essentially independent from tftp, and will also be utilised in implementing UEFI capsule update in a later commit. So just give it a more generic name. In addition, a new configuration option, CONFIG_DFU_ALT, was introduced so that the file will be compiled with different options, particularly one added in a later commit.
