Since Freescale developers monitor the meta-freescale mailing list,  is 
it acceptable to post any question or issue about FSL SDK SW 
(considering it's built with poky / bitbake)?   If there are 
intellectual property issues with this, then what are the guidelines to 
using the meta-freescale list?

I have noticed in the past some non-trivial QorIQ DPAA questions being 
asked on this board, but I have not seen a response by Freescale 
developers.  I have wondered whether the questions were ignored or 
answered privately.
