I'm just wondering if there's any overlap or conflict with the existing
dca feature - it seems that they at least have the CONFIG_INTEL_IOATDMA
option in common, so wondering whether the existing dca feature could
either use the ioatdma feature, or whether this new stuff could be using
the dca feature instead.  I'm not too familiar with it, so can't say off
the top of my head, just pointing it out in case you missed it...

features/dca/dca.cfg:

CONFIG_INTEL_IOATDMA=m

and features/dca/dca.scc:

define KFEATURE_DESCRIPTION "Enable DCA for IOATDMA capable devices"
define KFEATURE_COMPATIBILITY board

kconf hardware dca.cfg

include cfg/dmaengine.scc
