207conf/machine/crystalforest.conf is the common machine configuration
208to support Crystal Forest/server, Crystal Forest/gladden, Highland Forest and
209River Forest. In order to generate the right binary for these platforms which
210have different QAT technology, user could change the default config accordingly
211within crystalforest.conf as below:
212
213For Coleto Creek chipset:
214PREFERRED_PROVIDER_virtual/qat ?= "qat16"
215
216For Cave Creek chipset:
217PREFERRED_PROVIDER_virtual/qat ?= "qat15"

219Another option and preferred approach for above setting is to override
220configuration under build/conf/local.conf as follow:

222For Coleto Creek chipset:
223PREFERRED_PROVIDER_virtual/qat = "qat16"
