MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch adds the basic clocks and timer support for the Allwinner A20 (sun7i) processor. This code will not been compiled until the build is hooked up in a later patch. It has been split out to keep the patches manageable. Some of the code here is common to multiple sunxi subarchtectures, hence files are named sun4i which is the earliest similar variant.

It's "correct" in so far as it works (the boards.cfg config stuff #defines things to 1), but I think you are right that it isn't the preferred style. But... > A quick scan through this patch series shows that this define > is not set at all. Perhaps its outdated? Or is it used to support > some other sunxi SoC? Not sure, perhaps it should be removed for > now. ...I had thought that it was to support some other board which wasn't being upstreamed right now, so eventually useful and harmless for now, but I've just checked and it isn't actually used by any of the boards in u-boot-sunxi.git. So rather than fix it to use #ifdef lets drop it.
