[meta-intel] chiefriver BSP retirement from meta-intel layer

[Kamble, Nitin A]

To all the chiefriver BSP customers,

     The Chiefriver BSP was made for a specific ivy-bridge developement 
board. That board is not available anymore. On the other hand, the NUC 
BSP provides support for ivy-bridge CPU platforms which includes all the 
features of Chiefriver BSP, especially the AMT support. While 
considering these aspects, the Yocto Project BSP team is considering the 
chiefriver BSP for retirement before the Yocto Project 1.6 release. If 
anybody has any objections or concerns for retiring of the chiefriver 
BSP, then vice your concern by responding to this email. If no concern 
or response is received in a week from this email, then the chiefriver 
BSP will be removed from the meta-intel master branch, and will not be 
available in the Yocto Project 1.6 release. Also note that this will not 
remove the Chiefriver BSP support from any of the older Yocto Project 
releases, and the Chiefriver BSP will still be available publicly in 
Yocto Project 1.5 and older releases.
