[Buildroot] Merge window

[Joachim Nilsson]

Hi,

I'm new to the Buildroot community and am curious to learn more about
the development process, in particular if there is any merge window to
consider when submitting patches?  I've combed through the (fantastic)
documentation, but not found any mention of this.  Seeing as there are
a few brave souls who seem to do much of the legwork in this project,
I worry about the timing of patches and questions as to not wear down
or disturb at the wrong time.

I recently submitted my first patch to add support for the EspressoBin
which has not yet gotten any response.  So I'm thinking my timing was
bad, considering you seem to be preparing a new release, or maybe I
missed Cc:ing someone.  Should I resend the patch at a better time?

Best regards
