[Buildroot] [PATCH 1/1] beaglebone: better support for starting and creating images

[Stephan Hoffmann]

Hello community,

is there really no interest in this patch?

I personally think it would be a great improvement for beaglebone
support, but do not feel suficiently familiar with buildrooot to apply
Acked-by.

Kind regards

Stephan
