How about announcing (as in, "letting the whole world know by slipping
it in our public announcement of 2013.07") that custom prompts will be
deprecated starting with 2013.10 and that targets still having them by
2014.01 will be retired?

That's what we did for ARM ELF relocation IIRC.

Of course, that would require a few round of e-mails to maintainers, at
least to those whose targets' config header files still have custom
prompts when reaching 2014.01-rc1; and there will be some yelling that
such or such board has been dropped from U-Boot and why were users not
told, etc.

Alternatively, we could announce and deprecate in 2013.10 and remove
all custom prompts in 2013.14 ourselves, then wait for annoyed people
to yell at us, and advise them to enable CONFIG_ENV_VARS_UBOOT_CONFIG
and uptate their scripts. Less prep work, slightly more yelling.

We could even shift the schedule, deprecate for 2013.07 and remove in
2013.10. Same amount of work, yelling goes away earlier.

My vote goes to this last proposal. :)

Amicalement,
