[PATCH 0/6][SRU][F] Support Advantech UNO-420 platform

[AceLan Kao]

Those drivers are for dedicated hardware(project), there is no normal
user who will use those drivers.
And for current status, those drivers are submitting to upstream and
we hope they eventually could make their way into the mainline kernel.
So, I think we don't have to carry those drivers currently.
Will check their status and backport them if needed when they are
accepted by upstream.
